[chengdang]

This PR merges v2.4.1 surface emissivity updates into v3, major updates including:

• NetCDF I/O for all surface emissivity LUTs (except for MW water)
• Interface required for new IR emissivity tables: Nalli2.IRwater, Nalli.IRsnow and Nalli2.IRsnow
• Fix folder: (1) all IR water emissivity tables need to be updated for this branch to work; (2) new optional table Nalli2.IRsnow needs to be added to fix folder.
• All standalone CRTM ctests passed.

This branch contains all updates that is currently in develop branch and feature/cd_v241_cloud_aerosol_io

@chengdang can you resolve the conflict here, and verify that the provided coefficient tarball has the necessary files?

[chengdang]

@BenjaminTJohnson Conflict resolved.

Yes, you are right. The current tarball fix_REL-3.0.0_20230303.tgz does not have the updated files.
It needs to be updated:

• Replace fix/EmisCoeff/IR_Water with this folder for coefficient LUT Release updates (Release = 4): https://drive.google.com/file/d/19-nkyBKy7gcETjaf5VkKq4oecGOsD0eT/view?usp=drive_link
• Add new snow emissivity table.Nalli2.IRsnow.EmisCoeff.nc4 to folder fix/EmisCoeff/IR_Snow/Nalli/netCDF: https://drive.google.com/file/d/1Lc2tYOfsLespmJJwXkB2tm1QlUvTvTEX/view?usp=drive_link

Tarball is updated and uploaded to pub/s4/CRTM: fix_REL-3.0.0_20230802.tgz
Modified Get_CRTM_Binary_Files.sh.

I'm a bit confused about the version number (?) 9cf4b1cc57e20802e608a597d7f53073 CMakeFile.txt here: https://github.com/JCSDA/CRTMv3/blob/0cb4259fb7ece671ff65eb7ca65c159f1d1227fd/test/CMakeLists.txt#L82C87-L82C119, so I did not upload anything to pub/s4/CRTM/file/

[BenjaminTJohnson]

@chengdang I will test / merge this today. Sorry for the long delay.

[BenjaminTJohnson]

@chengdang I created PRs in the UFO and fv3-jedi internal repository to reflect the changes in the coefficients files and the update of the tarball name and md5sum values. As they're approved in UFO and fv3-jedi, merge this PR, then give them the go ahead to merge theirs.

[chengdang]

@BenjaminTJohnson I uploaded file crtm_coefficients_3.0.0_skylab_6.0.tar.gz.md5 to the s4 ftp site, per instruction by @fabiolrdiniz. This file is needed for UFO/FV3/MPAS-JEDI tests
