Decision Support System (DSS) for air quality

March 30, 2024

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.

About Decision Support System:

  • It 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.
