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".

A brief description of the chemical transport model FARM, "Flexible Air quality Regional Model" utilized for forecasting air quality over Delhi, India is presented here.
This system is developed by France based Aria Technologies SA and Leosphere SA, in technical collaboration with the Central Pollution Control Board of India. The system will pilot before the start of the Commonwealth Games to be held in October 2010. More details at forecasting modeling system for Delhi.
