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.
