Atmospheric dispersion modeling is the mathematical simulation of how air pollutants disperse in the ambient atmosphere. It is performed with computer programs that include algorithms to solve the mat

In meteorology, the planetary boundary layer, also known as the atmospheric boundary layer or peplosphere, is the lowest part of the atmosphere and its behaviour is directly influenced by its contact

…other layers above 80 km, but they are insignificant with respect to atmospheric dispersion modeling. The lowest part of the troposphere is called the planetary boundary layer (PBL), or sometimes the atmospheric boundary layer. The air temperature of the PBL decreases with increasing altitude until it reaches a capping…
Depiction of where the planetary boundary layer lies on a sunny day.
The difference in the amount of aerosols below and above the boundary layer is easy to see in this aerial photograph. Light pollution from the city of Berlin is strongly scattered below the layer, but above the layer it mostly propagates out into space.
