This European NO2 product is based on the operational TROPOMI NO2 offline (reprocessing) datasets, covering the full period from 30 April 2018 to roughly 7-10 days behind real time. The TROPOMI offline (OFFL) NO2 files are processed once they become available.
Using the averaging kernels and air-mass factors, the original a-priori profile shapes from the global TM5-MP model (resolution of 1x1 degree) are replaced by the daily CAMS European regional NO2 fields with an improved resolution of 0.1x0.1 degree. New a-priori tropospheric profiles for the retrieval are extracted from daily CAMS-regional ensemble analyses between the surface and 3km altitude, and from the daily CAMS-global analyses for altitudes between 3km and the tropopause.
The regional NO2 tropospheric column results are added to the existing operational Level2 OFFL NO2 datafiles, which are cropped to show only Europe. The relevant extra field in the L2 file has the name: "nitrogendioxide_tropospheric_column_CAMS_apriori_Europe" The datafiles with the European NO2 data may be recognised by the extension "eu", for instance: "S5P_OFFL_L2__NO2____20200407T105150_20200407T123320_12869_01_010302_20200409T033938_eu.nc"
