Abstract:
This product contains monthly mean tropospheric NO2 columns for Germany derived from Sentinel-5P/TROPOMI Level-1B data. The tropospheric NO2 data are vertical column densities with the unit "µmol/m2". Sentinel-5P observes Germany once per day at ~12:00 UTC and only cloud-free measurements (cloud fraction < ~0.2) are used.
The Sentinel-5P tropospheric NO2 data within each month are averaged and gridded onto a regular 2 km x 2 km UTM grid. The number of measurements used in the calculation of the averaged value are included in this product as well.
