Source of atmospheric profiles in Sentinel 3 SLSTR data


Can anyone point me in the direction of documents describing the nature and source of the atmospheric profiles under “Tie-Point grids” in Sentinel 3 SLSTR data? I’m having trouble finding any information about these online.

Many thanks!

Actually, the information you are looking for should be somewhere in of the documents you can find here:
But I haven’t found much about it. All I know is that the data is coming from ECMWF.
If you need to know more, it is better to contact the ESA TellUs service or the new rus-copernicus service.
