Dear authors,

Thank you for your detailed response to the referee reports and the revised manuscript. I think the paper can be published with some technical corrections based on your responses and the author's tracked changes. However, I think you have accidentally uploaded the initial version of the manuscript instead of the revised version. I therefore ask for a minor revision so that you can upload the correct version. Please also consider the following technical points:

(1) I suggest that you do not abbreviate the TROPOMI NO2 product with "DOAS", because the NASA Standard Product also uses a DOAS approach. I think this will be confusing to readers.

(2) You need to provide the GEOS-Chem, PGN, S5P Data Hub and LIS-OTD citations as references instead of a link in the text. If you have a DOI for the software/dataset, the reference does not require an access data. Access dates are only necessary for websites (but not for persistent identifiers such as DOIs).

Best regards
Gerrit Kuhlmann
