| At the moment, you can only have one sort of emitted component in the model (but you can have different sources at different locations). So the settings in the configuration file are applying to ALL sources in the model. | At the moment, you can only have one sort of emitted component in the model (but you can have different sources at different locations).

| ENVI-met can handle sources of particulate matter (PM) as well as gas sources. For the latter one, no chemical transformations are calculated in the model. The simulation of particle dispersion includes sedimentation and deposition at surfaces and plant leafs depending on the size and density of the particles. | ENVI-met can handle sources of particulate matter (PM) as well as gas sources.
