'''DISPERSION21''' (also called '''DISPERSION 2.1''') is a local scale [[Air pollution dispersion modeling|air pollution dispersion model]]<ref name=Turner/><ref name=Schnelle/><ref name=Beychok/> developed by the air quality research unit at [[SMHI]], the ''Swedish Meteorological and Hydrological Institute'', located in [[Norrköping]].<ref name=SMHI-Staff/>

The model is widely used in Sweden by local and regional environmental agencies, various industrial users, consultant services offered by SMHI and for educational purposes.
 
==Features and Capabilities==
 
Some of the basic features and capabilities of DISPLAY21 are: <ref name=MDS/>
 
*Source types: Multiple [[Air pollution dispersion terminology|point, area , and volume]] sources as well as street canyons.
*Source releases: [[Air pollution dispersion terminology|Surface, near surface and elevated sources]].
*Source locations: [[Air pollution dispersion terminology|Urban or rural locations]].
*Plume types: [[Air pollution dispersion terminology|Continuous or intermittent]] [[Air pollution dispersion terminology|buoyant plumes]]
*[[Atmospheric dispersion modeling|Plume dispersion]] treatment: [[Air pollution dispersion terminology|Gaussian model]] treatment using [[Green's function]]s and includes multiple reflections.
*Terrain types: Simple terrain with no more than 10 degree slopes.
*Building effects: [[Air pollution dispersion terminology|Building downwash]] algorithms are included.
*[[Meteorology|Meteorological]] data: The model includes a preprocessor to produce the meteorological parameters needed to characterize the atmospheric turbulence as well as to produce wind speed and direction profiles.
* The street canyon module includes some [[atmospheric chemistry]] for [[photochemistry|photochemical]] reactions.
