Annual Global surface level Nitrogen Dioxide (NO2) concentration levels (ppb) for years 1990-2020 ({1990,1995,2000}+{2005-2020}) provided at 1km spatial resolution. The data-set is results of combining multiple products such as a land use regression model (Larkin et al. 2017), a in-house OMI level 3 product, and other data-sets in order to adjust and correct for satellite pass time and cloud coverage. The NetCDF files can be found at this link: https://gwu.box.com/s/4wey4183hb0nlp3dg4wl02chca3nqnl9
