Hello everyone,
I am planning to compare RTTOV simulations with ATMS data from NOAA-20 and NOAA-21. Could you please confirm which coefficient files I should use and provide the download link for them?

Thank you!

Hi Parisa,

It is generally recommended to use the coefficients based on measured spectral responses where available. For NOAA-20/21 ATMS these are contained in this tarball:

Best wishes,
