Nitrogen Dioxide Surface-Level Annual Average Concentrations V1 (SFC_NITROGEN_DIOXIDE_CONC) at GES DISC

The Nitrogen Dioxide Surface-Level Annual Average Concentrations Product (SFC_NITROGEN_DIOXIDE_CONC) contains estimated global NO2 surface values derived using a Land Use Regression (LUR) model (based on 5220 NO2 monitors in 58 countries and land use variables) for the years 2010-2012. NO2 column densities from the Ozone Monitoring Instrument and MERRA-2 scale the concentrations to other years between 1990 and 2020. This product is part of NASA's Health and Air Quality Applied Sciences Team (HAQAST) effort.

The data are global over land and span the latitude range between 60 south and 75 north, gridded at 0.0083 degree resolution (array size is 43080 x 16200). Data variables include surface NO2, as well as latitude and longitude values. The data are written to files using the new version 4 netCDF format. The average file size is about 150 Megabytes.
