I am working of some toxic gases for my research paper using CO, HCHO, NO2, O3, SO2, CH4 based sentinel databases.

I would like to know the elevation above sea level when measuring the previously mentioned gases.


My best regards.

Hi @mostafa.ayek.1997 ,


Please check out the Product User Information for each product you mentioned.


For example, it is described in the Product User Manual Carbon Monoxide that the operational S5p level-2 processor employs the SICOR physics-based retrieval algorithm to determine CO total column abundances from Earth radiance measurements (8.5 Using the S5p/TROPOMI L2 Carbon Monoxide).
