To support Delhi’s air pollution management, we forecast ambient concentrations for all the criteria pollutants for the next 72-hours. The modeling domain covering Delhi and its satellite cities, extends 80 km in North to South and 80 km West to East, with a spatial resolution of 0.01 degrees (~1 km) and a temporal resolution of 1 hour. The modeled meteorology and concentration data fields are updated everyday at ~7:00 PM IST.
