SIM-air Modeling Tools

The SIM-air tools developed by UrbanEmissions.info are free to use. 

Please cite appropriately and if you have any questions on the tools, suggestions to improve the tools, or want to share your experiences while using the tools, please email here.

So far, the SIM-air family of tools include the following

  • The SIM-air Model (V1.3, V2.0, and V3.0) - An integrated air pollution analysis tool to go from estimating emissions to pollution to impacts for a set scenario and also perform optimization among options for better air quality; Browse under the "Modeling Tools/SIM-air" tab to access the case studies from various cities
  • VAPIS - Vehicular Air Pollution Information System - A vehicular emissions calculator to estimate and compare emissions inventory; including a repository of emission factor databases
  • smart-CART - Carbon Analysis for Road Transport - A simple calculator for carbon analysis along a road corridor; with flexibility to expand to other pollutants
  • Air Quality Index Calculator - A simplified calculator, which is commonly used in a number of cities across the world, designed to plug your monitoring data to estimate either real time or forecasted AQI
  • ATMoS Dispersion Model - The Atmospheric Transport Modeling System - A (fortran language based) simplified lagrangian dispersion model to generate transfer matrices for multiple source and multiple pollutant types; for direct input to the SIM-air model
  • V-Dust - An easy to use calculator for fugitive dust emissions due to the vehicles on the road

Along with the tools, we maintain SIM-air working paper series, where methodologies, applications, and references on the air pollution modeling, emissions inventories, source apportionment, air quality management, and co-benefits analysis from cities and regions are published. The series is an open-resource and available for free. However, please cite the articles appropriately when used.

Latest in the series are

  • SIM‐39‐2012 ‐‐ Urban air pollution and co-benefits analysis for Indian cities
  • SIM‐38‐2012 ‐‐ A Multi‐pollutant emissions inventory for National Capital Region of Delhi, India
  • SIM‐37‐2012 ‐‐ An Analysis of health & carbon co‐benefits for Pune, India
  • SIM‐36‐2011 ‐‐ Air Quality Forecasting System for Cities: Modeling Architecture for Delhi, India
  • SIM‐35‐2010 ‐‐ AQI for Delhi, India: Trend Analysis & Implications to 2010 CW Games
  • SIM‐34‐2010 ‐‐ Air Quality Index (AQI): Methodology & applications for public awareness in Cities

Regular updates on the SIM-air tools and the SIM-air working paper series are sent to the members of the SIM-air mailing list. If you want to join the list, please send an email to with a brief description of your research.
