Monthly and Annual US TROPOMI Surface NO2 Estimates (~1km × 1km)

Estimate of surface-level nitrogen dioxide (NO2) concentrations for the continental US at ~ 1km × 1km derived from TROPOMI data from a land-use regression model. The development of this dataset is documented in a manuscript in ES&T Air by Nawaz et al. and was originally developed for a time period of 2019-2022. This dataset estimates surface-level NO2 by combining satellite derived data (TROPOMI) with OpenStreetMaps and Google Earth Engine land-use information and ERA5 meteorology reanalysis data. This is version 2.01. (2026-03-09)
