This page presents - Particulate Matter (PM), originates from burning of fossil fuels in vehicles, power plants, domestic cooking and heating, fugitive road dust, and various industrial processes, Some PM also occurs naturally, originating from dust storms, forest and grassland fires, and living vegetation. The animation below is for PM with aerodynamic diameter less than 2.5 micron-meter.

The air quality forecasting system for the National Capital Region (NCR) of Delhi is now operational and issuing daily reports to inform on the movement of the criteria pollutants in the city. The daily reports are updated @ 6 AM with forecasts for 48 hours. More details on the program @ air quality forecasting system for Delhi.
The forecasting system is supported by the meteorological model WRF and 3D Eulerian chemical transport models CHIMERE/FARM, utilizes a geo-referenced and time-profiled emissions inventory (segregated into multiple sectors) @ 1km x 1km resolution over the NCR region. The daily updates from the system include
- Animations of hourly maps for the six criteria pollutant concentrations
- Animations of hourly maps for the meteorological fields
- Daily (24 hour) average concentrations for the six criteria pollutants
- Air Quality Index (AQI) @ 37 locations in Delhi
- Time series of pollutant concentrations @ select locations
- Vertical profiles @ select locations (available up on request)
- An interface with "google earth".
