The air quality forecasting system for the National Capital Region (NCR) of Delhi issues daily report on the movement of the criteria pollutants for the next three days. These reports are updated @ 7 PM (IST).
The report includes information on pollutant concentrations (for PM10, PM2.5, SO2, NO2, CO, and O3) and the meteorological conditions. The meteorological data is extracted using the WRF meteorological model (coupled with NCEP/GFS weather forecasts) and the concentrations are extracted using the 3D Eulerian chemical transport model - CAMx and a geo-referenced/time-profiled emissions inventory @ 1km x 1km resolution over the NCR region (domain covers an area of 80km x 80km).
More details on Air Quality in Delhi.
The daily updates from the system include
- Animations of hourly concentration for PM10, PM2.5, SO2, NO2, CO, and O3
- Animations of hourly maps for the meteorological conditions
- Daily (24 hour) average concentrations for PM10, PM2.5, SO2, NO2, CO, and O3
- Air Quality Index (AQI) @ 22 locations in Delhi
- Time series of pollutant concentrations @ select locations
