SIM-air V1.3 allows for a 1-year snapshot analysis for a city or region. The tool calculates emissions for five sectors - transport, industry, residential, fugitive, and garbage burning, and grid-wise concentrations of primary and secondary pollutants. SIM allows for health impacts analysis and optimization of options.
The Simplified Atmospheric Transport Modeling System (ATMoS-4.0) is a linux/UNIX based "Lagrangian puff transport" dispersion model. It generates the source-receptor transfer matrix that is an integral part of the SIM-air model.
Vehicular Air Pollution Infomation System (VAPIS) is a demo tool that calculates transport sector emissions for one pollutant (eg. PM, SO2, NOx, CO, CO2, HC), for one category of vehicles (eg. buses, cars, trucks, motorcycles, 3-wheelers).
