Airshed

An airshed is a part of the atmosphere that behaves in a coherent way with respect to the dispersion of emissions. Alternatively, an airshed is a geographical area where local topography and meteorology limit the dispersion of pollutants away from the area.[1] They are formed by air masses moving across a landscape where they influence atmospheric composition. Their boundaries are loosely defined, but they can be quantified.[2]
