This collection contains monthly mean surface NO2 concentrations for Germany derived from Sentinel-5P/TROPOMI data. The Sentinel-5P NO2 data is generated by DLR and provided in the framework of the mFUND-Project "S-VELD".

The surface NO2 data are concentrations with the unit "µg/m3". Sentinel-5P observes Germany on a daily basis. Only cloud-free measurements (cloud fraction < ~0.2) are used and a strict data quality filter is applied to the Sentinel-5P data which can result in limited spatial coverage (especially in the winter months). The Sentinel-5P surface NO2 data within each month are averaged and gridded onto a regular UTM grid. The number of measurements used in the calculation of the averaged value are included in this collection as well.
