PM, SO2, NOx, CO, O3, VOCs modelled

Every Environmental Clearance application requires air quality impact assessment. This simplified Gaussian plume model calculates ground-level concentrations from your stack emissions, compares against NAAQS, and shows the concentration-distance profile. Use for preliminary screening before commissioning full AERMOD studies.
