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 management framework, modeled hourly average ambient concentrations for the next 72 hours were simulated using meteorology processed through 3D-WRF meteorological model and the GFS meteorological fields and the concentrations simuated through the CAMx chemical transport modeling system.
The 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. Click on the pollutant to access the animations.
