Abstract
The dataset was produced as part of the European Space Agency (ESA) Climate Change Initiative+ (CCI+) precursors for aerosols and ozone project by the Royal Netherlands Meteorological Institute (KNMI).
Ozone Monitoring Instrument (OMI) global tropospheric nitrogen dioxide (NO2) spatiotemporally averaged per month over a standard grid from October 2004 to March 2021. The dataset is provided in four different spatial resolutions: 0.2x0.2 (900x1800 grid cells), 0.5x0.5 (360x720), 1x1 (180x360), 2x2.5 (91x144) and includes auxiliary variables (e.g. cloud and surface properties, propagated level 3 uncertainties, averaging kernels). The data are provided in monthly netCDF files for each spatial resolution. doi: https://doi.org/10.21944/cci-no2-omi-l3
