Following crtm user guide, I run the following command to get the coefficients:
But I found the folder ‘fix’ doesn’t contain the ODAS TauCoeff for noaa20 ATMS. Could you tell me where I can get these coefficients?
I tested the ODAS and ODPS on crtm 2.1.3 for NPP and the results are quite different. I’m using EC as input. The temperature (K), humidity (mass mixing ratio g/kg) and O3 (volume mixing ratio ppmv) are provided on pressure levels (hpa). Should I use ODAS or ODPS? What is the difference between them?
