Estimated surface NO2 over Europe for the year 2019-2021

These datasets consist of estimated daily surface NO₂ concentrations over Europe at ~1km spatial resolution in tiff file format generated using S-MESH model and is part of the research article https://doi.org/10.1016/j.rse.2024.114321.  Files are zipped into 3 folders each corresponding to a year and can be unzipped from command line using "tar -xvzf filename.tar.gz". Each file represents surface NO₂ during the Sentinel-5P satellite overpass time and the file is named based on the date of measurement. Each tiff file is a single band image with an extent of 25°W-42.5°E & 29.9-74.28°N in EPSG:4326 - WGS 84 projection. The surface NO₂ concentrations are estimated using Sentinel-5P TROPOMI tropospheric column density and a XGBoost machine learning model. The overall median absolute error of the model predictions across Europe is 4.43μg/m³
