Decision Support System : Air Quality Check

The Decision Support System (DSS), which identifies sources of pollution in Delhi’s air, will resume functioning from Sept this year with some new features

  • Decision Support System is a numerical model-based framework to forecast Delhi’s air quality and sources of local and regional pollution which can impact the air. It is developed by Indian Institute of Tropical Meteorology (IITM) Pune.
  • It provides quantitative information about:
    • The contribution of emissions from Delhi and the surrounding 19 districts
    • The contribution of emissions from 8 different emission sectors in Delhi
    • The contribution from biomass-burning activities in the neighboring states
    • The effects of possible emission source-level interventions on the forecast
    • The system, which works only in winter and is stopped from March to August.
  • The two models — System of Air Quality and Weather Forecasting And Research (Safar) and DSS — had temporarily stopped sharing data on air pollution for the country as there were differences between their forecasts and source contribution.
