Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Oman
–
Oman, officially the Sultanate of Oman, is an Arab country on the southeastern coast of the Arabian Peninsula. The coast is formed by the Arabian Sea on the southeast, the Madha and Musandam exclaves are surrounded by the UAE on their land borders, with the Strait of Hormuz and Gulf of Oman forming Musandams coastal boundaries. From the late 17th century, the Omani Sultanate was an empire, vying with Portugal and Britain for influence in the Persian Gulf. At its peak in the 19th century, Omani influence or control extended across the Strait of Hormuz to modern-day Iran and Pakistan, as its power declined in the 20th century, the sultanate came under the influence of the United Kingdom. Historically, Muscat was the trading port of the Persian Gulf region. Muscat was also among the most important trading ports of the Indian Ocean, the Sultan Qaboos bin Said al Said has been the hereditary leader of the country since 1970. Sultan Qaboos is the current ruler in the Middle East. Oman has modest oil reserves, ranking 25th globally, nevertheless, in 2010 the UNDP ranked Oman as the most improved nation in the world in terms of development during the preceding 40 years. A significant portion of its economy is tourism and trade of fish, dates and this sets it apart from its neighbors solely oil-dependent economies. Oman is categorized as an economy and ranks as the 74th most peaceful country in the world according to the Global Peace Index. Two optically stimulated luminescence age estimates place the Arabian Nubian Complex at 106,000 years old and this supports the proposition that early human populations moved from Africa into Arabia during the Late Pleistocene. Dereaze, located in the city of Ibri, is the oldest known settlement in the area. Archaeological remains have been discovered here from the Stone Age and the Bronze Age, findings have included stone implements, animal bones, shells and fire hearths, with the latter dating back to 7615 BC as the oldest signs of human settlement in the area. Other discoveries include hand-molded pottery bearing distinguishing pre-Bronze Age marks, heavy flint implements, pointed tools, sumerian tablets refer to a country called Magan or Makan, a name believed to refer to Omans ancient copper mines. Mazoon, another used for the region, is derived from the word muzn. The present-day name of the country, Oman, is believed to originate from the Arab tribes who migrated to its territory from the Uman region of Yemen. Many such tribes settled in Oman, making a living by fishing, herding or stock breeding, from the 6th century BC to the arrival of Islam in the 7th century AD, Oman was controlled and/or influenced by three Persian dynasties, the Achaemenids, Parthians and Sassanids. A few scholars believe that in the 6th century BC, the Achaemenids exerted a strong degree of control over the Omani peninsula, Central Oman has its own indigenous so-called Late Iron Age cultural assemblage, the Samad al-Shan

Arabic language
–
Arabic is a Central Semitic language that was first spoken in Iron Age northwestern Arabia and is now the lingua franca of the Arab world. Arabic is also the language of 1.7 billion Muslims. It is one of six languages of the United Nations. The modern written language is derived from the language of the Quran and it is widely taught in schools and universities, and is used to varying degrees in workplaces, government, and the media. The two formal varieties are grouped together as Literary Arabic, which is the language of 26 states. Modern Standard Arabic largely follows the standards of Quranic Arabic. Much of the new vocabulary is used to denote concepts that have arisen in the post-Quranic era, Arabic has influenced many languages around the globe throughout its history. During the Middle Ages, Literary Arabic was a vehicle of culture in Europe, especially in science, mathematics. As a result, many European languages have borrowed many words from it. Many words of Arabic origin are found in ancient languages like Latin. Balkan languages, including Greek, have acquired a significant number of Arabic words through contact with Ottoman Turkish. Arabic has also borrowed words from languages including Greek and Persian in medieval times. Arabic is a Central Semitic language, closely related to the Northwest Semitic languages, the Ancient South Arabian languages, the Semitic languages changed a great deal between Proto-Semitic and the establishment of the Central Semitic languages, particularly in grammar. Innovations of the Central Semitic languages—all maintained in Arabic—include, The conversion of the suffix-conjugated stative formation into a past tense, the conversion of the prefix-conjugated preterite-tense formation into a present tense. The elimination of other prefix-conjugated mood/aspect forms in favor of new moods formed by endings attached to the prefix-conjugation forms, the development of an internal passive. These features are evidence of descent from a hypothetical ancestor. In the southwest, various Central Semitic languages both belonging to and outside of the Ancient South Arabian family were spoken and it is also believed that the ancestors of the Modern South Arabian languages were also spoken in southern Arabia at this time. To the north, in the oases of northern Hijaz, Dadanitic and Taymanitic held some prestige as inscriptional languages, in Najd and parts of western Arabia, a language known to scholars as Thamudic C is attested

Muscat, Oman
–
Muscat is the capital and largest metropolitan city of Oman. It is also the seat of government and largest city in the Governorate of Muscat, according to the National Centre for Statistics and Information, the total population of Muscat Governorate reached 1.56 million as of September 2015. The metropolitan area spans approximately 3,500 km2 and includes six provinces called wilayats, a regional military power in the 18th century, Muscats influence extended as far as East Africa and Zanzibar. As an important port-town in the Gulf of Oman, Muscat attracted foreign tradesmen and settlers such as the Persians and the Balochis. Since the ascension of Qaboos bin Said as Sultan of Oman in 1970, Muscat has experienced rapid development that has led to the growth of a vibrant economy. The rocky Western Al Hajar Mountains dominate the landscape of Muscat, the city lies on the Arabian Sea along the Gulf of Oman and is in the proximity of the strategic Straits of Hormuz. Low-lying white buildings typify most of Muscats urban landscape, while the port-district of Muttrah, with its corniche and harbour, Muscats economy is dominated by trade, petroleum and porting. Ptolemys Map of Arabia identifies the territories of Cryptus Portus and Moscha Portus, scholars are divided in opinion on which of the two related to the city of Muscat. Similarly, Arrianus references Omana and Moscha in Voyage of Nearchus, interpretations of Arrianus work by William Vincent and Jean Baptiste Bourguignon dAnville conclude that Omana was a reference to Oman, while Moscha referred to Muscat. Similarly, other scholars identify Pliny the Elders reference to Amithoscuta to be Muscat, the origin of the word Muscat is disputed. Some authors claim that the word has Arabic origins – from moscha, other authors claim that the name Muscat means anchorage or the place of letting fall the anchor. Other derivations include muscat from Old Persian, meaning strong-scented, or from Arabic, meaning falling-place, Cryptus Portus is synonymous with Oman. But Ov-man, and the old Sumerian name Magan, means sea-people in Arabic, an inhabitant is a Muscatter, Muscatian, Muscatite or Muscatan. Evidence of communal activity in the area around Muscat dates back to the 6th millennium BCE in Ras al-Hamra, the graves appear to be well formed and indicate the existence of burial rituals. South of Muscat, remnants of Harappan pottery indicate some level of contact with the Indus Valley Civilisation. Muscats notability as a port was acknowledged as early as the 1st century CE by the Greek geographer Ptolemy, who referred to it as Cryptus Portus, and by Pliny the Elder, who called it Amithoscuta. The port fell to a Sassanid invasion in the 3rd century CE, under the rule of Shapur I, Muscats importance as a trading port continued to grow in the centuries that followed, under the influence of the Azd dynasty, a local tribe. The establishment of the First Imamate in the 9th century CE was the first step in consolidating disparate Omani tribal factions under the banner of an Ibadi state, however, tribal skirmishes continued, allowing the Abbasids of Baghdad to conquer Oman

Seeb International Airport
–
Muscat International Airport, formerly Seeb International Airport, is the main international airport in Oman. It is situated 32 km from the old city and capital Muscat within the Muscat metropolitan area, the airport serves as the hub for flag carrier Oman Air and features flights to several regional destinations as well as some intercontinental services to Asia, Africa and Europe. The airport opened as Seeb International Airport in 1973, replacing a smaller airfield located in Bayt al Falaj and it has hosted Royal Air Force BAe Nimrods in the past, including for the 1991 Gulf War. These aircraft cooperated with the Royal Navy of Oman in the Magic Roundabout exercise series, the base was used by a detachment of Vickers VC10 tankers from No.101 Squadron RAF during the Gulf War training with Royal Air Force SEPECAT Jaguars. As of 1 February 2008, the name has been changed from Seeb International Airport to Muscat International Airport. The entire airport is spread over an area of 21 square kilometres, the new facilities are undergoing completion and testing as of March 2017. The airport currently features one single, two-storey passenger terminal and it has a T-shape and is equipped with 58 check-in counters,23 departure gates,3 baggage reclaim belts and some service counters and shops. The building, dating from the 1970s, has expanded several times during the last years to cater for growing passenger numbers. However, it still has no aircraft equipped with jet-bridges. The existing terminal will be renamed to Terminal 2 once the new terminal becomes fully operational, the current terminal will be replaced with an entirely new and significantly larger state-of-the-art facility to the north of the existing terminal and first runway. This new building, which is under construction as of March 2017, subsequent enlargements under second and third phases will increase the airport capacity to 24 and 48 million annual passengers respectively. The first stage will cover 580,000 sqm and will feature 86 check-in counters,10 baggage reclaim belts,29 aircraft stands with jet-bridges as well as a new control tower. The new terminal is located between the old and new runways and will be able to large aircraft such as Airbus A380s. As of March 2017, the new terminal is planned to start operations at the end of 2017, the airport used to have a single runway. The airport is capable of handling aircraft up to the size of a Boeing 747-8. All 108 passengers and crew were safe, the aircraft, a Boeing 737, has landed tilting on the left and the landing gear on the left of aircraft appears to have broken. The airport is located near the Sultan Qaboos Highway between Muscat and Seeb, taxis, car hire and chauffeur services are available. Public buses stop in front of the area on the highway

Desert climate
–
An area that features this climate usually experiences from 25 to 200 mm per year of precipitation and in some years may experience no precipitation at all. Averages may be even less such as in Arica, Chile, there are usually two or three variations of a desert climate, a hot desert climate, a cold desert climate and, sometimes, a mild desert climate. To determine whether a location has a climate, the precipitation threshold is determined. If the areas precipitation is less than half the threshold. Hot desert climates are found under the subtropical ridge where there is largely unbroken sunshine for the whole year due to the stable descending air. These areas are located between 30 degrees south and 30 degrees north latitude, under the subtropical latitudes called the horse latitudes, hot desert climates are generally hot, sunny and dry year-round. Hot desert climates also reach similar latitudes in the Middle East, North Africa, hot desert climates usually feature hot, sometimes exceptionally hot, periods of the year. In many locations featuring a hot climate, maximum temperatures of over 40 °C are not uncommon in summer. The world absolute heat records, over 50 °C, are generally in the hot deserts, some desert locations consistently experience very high temperatures all year long, even during wintertime. These locations feature some of the highest annual average temperatures recorded on Earth and this last feature is seen in some parts of deserts of Africa and Arabia. During colder periods of the year, night-time temperatures can drop to freezing or below due to the radiation loss under the clear skies. However, very rarely do temperatures drop far below freezing, only one region in Europe has a hot desert climate, Province of Almeria, Province of Alicante and Province of Murcia in South Eastern Spain. Cold desert climates usually feature warm and dry summers, though summers typically are not quite as hot as summers in hot desert climates, unlike hot desert climates, cold desert climates tend to feature cold winters with rare snow. Cold desert climates are found at higher altitudes than hot desert climates. A cold desert climate is found in temperate zones, usually in the rain shadow of high mountains. A classic example of this is the Patagonian Desert in Argentina bounded by the Andes to its west, in the case of Central Asia, mountains restrict precipitation from the monsoon. The Gobi desert in Mongolia is an example of this. Though hot in summer, it shares the cold winters of the rest of Central Asia

Precipitation
–
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include drizzle, rain, sleet, snow, graupel, Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and precipitates. Thus, fog and mist are not precipitation but suspensions, because the vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated, Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers, moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into clouds and rain. This process is active when freezing rain is occurring. A stationary front is often present near the area of freezing rain, provided necessary and sufficient atmospheric moisture content, the moisture within the rising air will condense into clouds, namely stratus and cumulonimbus. Eventually, the droplets will grow large enough to form raindrops. Lake-effect snowfall can be locally heavy, thundersnow is possible within a cyclones comma head and within lake effect precipitation bands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation, on the leeward side of mountains, desert climates can exist due to the dry air caused by compressional heating. The movement of the trough, or intertropical convergence zone. Precipitation is a component of the water cycle, and is responsible for depositing the fresh water on the planet. Approximately 505,000 cubic kilometres of water falls as precipitation each year,398,000 cubic kilometres of it over the oceans and 107,000 cubic kilometres over land. Given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres, Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes. Precipitation may occur on celestial bodies, e. g. when it gets cold, Mars has precipitation which most likely takes the form of frost. Precipitation is a component of the water cycle, and is responsible for depositing most of the fresh water on the planet. Approximately 505,000 km3 of water falls as precipitation each year,398,000 km3 of it over the oceans, given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres. Mechanisms of producing precipitation include convective, stratiform, and orographic rainfall, Precipitation can be divided into three categories, based on whether it falls as liquid water, liquid water that freezes on contact with the surface, or ice

Relative humidity
–
Relative humidity is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest and it requires less water vapor to attain high relative humidity at low temperatures, more water vapour is required to attain high relative humidity in warm or hot air. Humans are sensitive to high humidity because the body uses evaporative cooling, enabled by perspiration. Perspiration evaporates from the more slowly under humid conditions than under arid. For example, if the air temperature is 24 °C and the humidity is zero percent. If the relative humidity is 100 percent at the air temperature. In other words, if the air is 24 °C and contains saturated water vapor, then the human body cools itself at the rate as it would if it were 27 °C. The heat index and the humidex are indices that reflect the effect of temperature. In cold climates, the temperature causes lower capacity for water vapour to flow about. Dry cracked skin can result from dry air, low humidity causes tissue lining nasal passages to dry, crack and become more susceptible to penetration of Rhinovirus cold viruses. Low humidity is a cause of nosebleeds. The use of a humidifier in homes, especially bedrooms, can help with these symptoms, indoor relative humidities should be kept above 30% to reduce the likelihood of the occupants nasal passages drying out. Humans can be comfortable within a range of humidities depending on the temperature—from thirty to seventy percent—but ideally between 50% and 60%. Very low humidity can create discomfort, respiratory problems, and aggravate allergies in some individuals, in the winter, it is advisable to maintain relative humidity at 30 percent or above. Extremely low relative humidities may also cause eye irritation, wooden furniture can shrink, causing the paint that covers these surfaces to fracture. When the temperature is low and the humidity is high. When relative humidity approaches 100 percent, condensation can occur on surfaces, leading to problems with mold, corrosion, decay, condensation can pose a safety risk as it can promote the growth of mold and wood rot as well as possibly freezing emergency exits shut. The basic principles for buildings, above, also apply to vehicles, in addition, there may be safety considerations

Sunshine duration
–
It is a general indicator of cloudiness of a location, and thus differs from insolation, which measures the total energy delivered by sunlight over a given period. Sunshine duration is usually expressed in hours per year, or in hours per day, the first measure indicates the general sunniness of a location compared with other places, while the latter allows for comparison of sunshine in various seasons in the same location. Another often-used measure is percentage ratio of recorded bright sunshine duration, an important use of sunshine duration data is to characterize the climate of sites, especially of health resorts. This also takes account the psychological effect of strong solar light on human well-being. It is often used to promote tourist destinations, if the Sun were to be above the horizon 50% of the time for a standard year consisting of 8,760 hours, apparent maximal daytime duration would be 4,380 hours for any point on Earth. However, there are physical and astronomical effects that change that picture, namely, atmospheric refraction allows the Sun to be still visible even when it physically sets below the horizon. For that reason, average daytime is longest in polar areas, places on the Arctic Circle have the longest total annual daytime,4,647 hours, while the North Pole receives 4,575. Because of elliptic nature of the Earths orbit, the Southern Hemisphere is not symmetrical, the Equator has a total daytime of 4,422 hours per year. Given the theoretical maximum of daytime duration for a given location, bright sunshine hours represent the total hours when the sunlight is stronger than a specified threshold, as opposed to just visible hours. Visible sunshine, for example, occurs around sunrise and sunset, measurement is performed by instruments called sunshine recorders. For the specific purpose of sunshine duration recording, Campbell–Stokes recorders are used, when the intensity exceeds a pre-determined threshold, the tape burns. The total length of the trace is proportional to the number of bright hours. Another type of recorder is the Jordan sunshine recorder, newer, electronic recorders have more stable sensitivity than that of the paper tape. In 2003, the duration was finally defined as the period during which direct solar irradiance exceeds a threshold value of 120 W/m². The sky is clear in these regions, and fair weather is virtually perpetual, the descending branch of the Hadley cell and the long-term lack of atmospheric disturbances helps to explain the seemingly endless supply of sunny, cloud-free days in the deserts. Low clouding conditions are associated with rainfall shortage, as seen in these dry regions. In the belt encompassing northern Chad and the Tibesti Mountains, northern Sudan, southern Libya, some places in the interior of the Arabian Peninsula receive 3, 600–3,800 hours of bright sunshine annually. The largest sun-baked region in the world is North Africa, the sunniest month in the world is December in Eastern Antarctica, with almost 23 hours of bright sun daily

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker

The National Oceanic and Atmospheric Administration is an American scientific agency within the United States Department of Commerce focused on the conditions of the oceans and the atmosphere. NOAA warns of dangerous weather, charts seas, guides the use and protection of ocean and coastal resources, and conducts research to improve understanding and stewardship of the environment. In addition to its employees, over 11,000 as of 2015, NOAA research. NOAA plays several roles in society, the benefits of which extend beyond the U. S. economy and into the larger global community. NOAA supplies information to its customers and partners pertaining to the state of the oceans and this is clearly manifest in the production of weather warnings and forecasts through the National Weather Service, but NOAAs information products extend to climate, ecosystems, and commerce as well. A Provider of Environmental Stewardship Services, NOAA is also the steward of U. S. coastal and marine environments. A Leader in Applied Scientific Research, the five fundamental activities are, Monitoring and observing Earth systems with instruments and data collection networks. Understanding and describing Earth systems through research and analysis of that data, assessing and predicting the changes of these systems over time. Engaging, advising, and informing the public and partner organizations with important information, managing resources for the betterment of society, economy and environment. NOAA formed a conglomeration of several existing agencies that were among the oldest in the federal government, NOAA was established within the Department of Commerce via the Reorganization Plan No.4 of 1970. In 2007 NOAA celebrated 200 years of service with its ties to the United States Coast, the NOAA Commissioned Officer Corps is a uniformed service of men and women who operate NOAA ships and aircraft, and serve in scientific and administrative posts. And in addition more than a dozen staff offices, including the Office of the Federal Coordinator for Meteorology, the NOAA Central Library and this is done through a collection of national and regional centers,13 river forecast centers, and more than 120 local weather forecast offices. They are charged with issuing weather and river forecasts, advisories, watches and they issue more than 734,000 weather and 850,000 river forecasts, and more than 45,000 severe weather warnings annually. NOAA data is relevant to the issues of global warming. The NWS operates NEXRAD, a network of Doppler weather radars which can detect precipitation. Many of their products are broadcast on NOAA Weather Radio, a network of transmitters that broadcasts weather forecasts, severe weather statements, watches. The National Ocean Service focuses on ensuring that ocean and coastal areas are safe, healthy, in 1960 TIROS-1, NOAAs first owned and operated geostationary satellite was launched. Since 1966 NESDIS has managed polar orbiting satellites and since 1974 it has operated geosynchronous satellites, in 1979 NOAAs first polar-orbiting environmental satellite was launched

A Qanāt or karez/kariz is a gently sloping underground channel to transport water from an aquifer or water well to surface for irrigation and drinking. The qanat technology is known to have developed in Iran by the Persian people sometime in the early 1st millennium BC. Qanat is the Arabic word for channel, Qanats in Persian called kārīz, kahan, Kahn, kahriz/kəhriz, khettara, Canal, falaj or foggara/fughara. Alternative terms for qanats in Asia and North Africa are kakuriz, chin-avulz, common variants of qanat in English include kanat, khanat, kunut, kona, konait, ghanat, ghundat. Qanats are constructed as a series of vertical shafts, connected by gently sloping tunnels. Qanats efficiently deliver large amounts of water to the surface without need for pumping. The water drains by gravity, typically from an upland aquifer, Qanats allow water to be transported over long distances in hot dry climates without much water loss to evaporation. The qanat should not be confused with the spring-flow tunnel typical to the area around Jerusalem. Although both are excavated tunnels designed to extract water by gravity flow, there are crucial differences, firstly, the origin of the qanat was a well that was turned into an artificial spring. In contrast, the origin of the tunnel was the development of a natural spring to renew or increase flow following a recession of the water table. Secondly, the shafts essential for the construction of qanats are not essential to spring-flow tunnels and it is very common for a qanat to start below the foothills of mountains, where the water table is closest to the surface. From this source, the tunnel slopes gently downward, slowly converging with the steeper slope of the land surface above. To connect a populated or agricultural area with an aquifer, qanats must often extend for long distances, Qanats are sometimes split into an underground distribution network of smaller canals called kariz. Like qanats, these canals are below ground to avoid contamination and evaporation. In some cases water from a qanat is stored in a reservoir, an ab anbar is an example of a traditional Persian qanat-fed reservoir for drinking water. The qanat system has the advantage of being resistant to disasters such as earthquakes and floods. Furthermore, it is almost insensitive to the levels of precipitation, from a sustainability perspective, qanats are powered only by gravity, and thus have low operation & maintenance costs once built. Qanats transfer freshwater from the plateau to the lower-lying plains with saltier soil
