Dataset for: Importance of satellite observations for high-resolution mapping of near-surface NO2 by machine learning

Dataset for: Importance of satellite observations for high-resolution mapping of near-surface NO2 by machine learning This dataset is uploaded as a part of the article by Kim et al. (2021). The dataset is the hourly maps of near-surface nitrogen dioxide (NO2) concentrations at 100 m resolution for an Alpine domain (Switzerland and northern Italy, 6-12 °E, 42-48 °N). The dataset is provided per day (24 hours) in a netcdf (*.nc ~550MB). In this work, we have generated NO2 hourly maps for Feb. 2019 to May 2020 and, here, we upload for March 2019 only (~16 GB). If you need data for another period of time, please contact Gerrit Kuhlmann ([e-mail]) or Minsu Kim ([e-mail]).
