Hey guys,
I want to download CAMS global reanalysis (EAC4) and I am trying to decide if I should download the model level 60 or the pressure level 1000 hPa. Since I think it would be better to have a stable geopotential altitude I thought of using the model level 60 which has a geopotential altitude of 10 meters. But when I checked the differences in NO2 between model 60 and the pressure level 1000 hPa I noticed that the NO2 concentration values are fairly different between them, which does not make much sense.
Could you explain me the difference between these 2 and why am I getting very different NO2 values?
Thanks in advance
