To support India’s air pollution modeling framework, we processed the NCEP Reanalysis global meteorological fields for 2015 through the 3D-WRF meteorological model. We have presented a summary for 640 districts on this page. The processed data is available for each of the districts as a text file (at the bottom, after you select state and district), which includes hourly surface wind speed, surface wind direction, precipitation, surface temperature, and mixing height – key parameters which determine the intensity of dispersion of emissions in the region. An infographic to the right shows prevalent wind directions in 16 major cities and a summary of all the meteorological parameters over Delhi is presented here.
