Description: The NASA Health and Air Quality Applied Sciences Team created a high-resolution dataset of surface-level NO2 concentrations globally for 2019 at 1km resolution. The surface NO2 combines land use regression, OMI NO2 data (L2 and L4-surface), and chemical transport modeling (Anenberg, Mohegh et al. https://doi.org/10.1016/S2542-5196(21)00255-2, see supplement pg 1-3). This service provides the 2019 year’s gridded data averaged within the 2010 decadal census block group levels (as in Kerr et al. https://doi.org/10.1073/pnas.2022409118) in units of parts per billion.
