Air pollution has emerged as a top-10 risk factor for human health in India and the cities are increasing exceeding the national ambient standards and the World Health Organizations guidelines for criteria pollutants. To support India’s air pollution management framework, modeled 24-hr (daily) average ambient concentrations were simulated for the next 72-hours, using meteorology processed through 3D-WRF meteorological model and the GFS meteorological fields and the concentrations simulated through the CAMx chemical transport modeling system.
The modeling domain covers the Indian sub-continent, which extends 32 degrees each longitudes and latitudes, at a spatial resolution of 0.25 x 0.25 degrees (~25 km 25 km) and a temporal resolution of 1 hour.
The 24-hr average modeled data fields are updated everyday at ~7:00 PM local time.
Particulate Matter (less than 2.5 micron-m) (PM2.5)
Particulate Matter (less than 10 micron-m) (PM10)
Sulfur Dioxide (SO2)
Nitrogen Dioxide (NO2)
Nitrogen Oxides (NOx = NO+NO2)
Carbon Monoxide (CO)
