Delhi Air Quality Forecasts – Meteorology

Air pollution has emerged as a major challenge in Delhi and the problem becomes more complex due to multiplicity and complexity of the mix of emission sources, such as, industries, automobiles, generator sets, domestic fuel burning, road side dusts, construction activities, etc. To support Delhi’s air pollution modeling framework, the meteorological forecasts are conducted using the 3D-WRF meteorological model and the GFS meteorological fields, in four geographical nests, which an integral feature of the WRF model. The fourth nest is the designated modeling domain covering Delhi and its satellite cities, which 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 data fields are updated everyday at ~7:00 PM local time.
