The DLR Geoservices web-server contains tropospheric NO2 column data from the Sentinel-5P/TROPOMI satellite instrument (for Germany and its surrounding regions):
https://download.geoservice.dlr.de/SVELD/files/

The data product is an outcome of the S-VELD project, which is funded by the German Federal Ministry of Transport and Digital Infrastructure in the framework of the mFUND-Programme (FKZ: 19F2065A).

Two types of Sentinel-5P/TROPOMI tropospheric NO2 products are available:

1) "Daily/Orbit" product containing tropospheric NO2 column data files for each orbit covering Germany (and its surrounding regions).
The daily products are stored in zip-files in the sub-directory: 'daily/'
The file name has the folllowing structure: S5P_TROPOMI_NO2_DAILY_YYYYMMDD.zip 

2) "Monthly" product containing monthly averaged tropospheric NO2 column data covering Germany (and its surrounding regions).
The monthly products are stored in zip-files in the sub-directory: 'monthly/'
The file name has the folllowing structure: S5P_TROPOMI_NO2_MONTH_YYYYMM.zip

Quick look images are included in the zip-file for download.

To download multiple data-files from the DLR Geoservices web-server, you can use download software such as "wget" and "curl".
For example, you can use the following "wget" command to download all daily products for one month:
"wget -r -nH --cut-dirs=4 https://download.geoservice.dlr.de/SVELD/files/daily/YYYY/MM/"

The product user manual (PUM) for the Sentinel-5P/TROPOMI NO2 products can be downloaded at:
