1 Release Notes: CRTM library v2.3.0
5 v2.3.0 - released November 21, 2017
7 * Made scientific changes to include:
8 1. All-Sky radiance simulation under cloud_fraction condition.
9 2. Use of all-sky transmittances in FASTEM-X reflection correction.
10 3. Improve surface reflectance in radiative transfer calculation for Microwave under
12 4. Add ATMS SeaIce emissivity module.
13 5. Fix the simulation near 3.9 mscron by adding solar contribution in ADA_Module.
14 6. Updates of CRTM Coefficients for ABI_GOES-R, AHI_Himawari-8.
15 7. Updates of CRTM antenna correction coefficients for MHS_N19/Metop-a.
16 8. Update AIRS coefficients for including NLTE correction.
17 9. Add new coefficients for: CrIS-fsrB1/B2/B3_NPP, CrIS*_N20, CrIS-fsr431_npp/n20,
18 AHI_Himawari-9, ABI_G16, VIIRS-JPSS1, ATMS_N20, ATMS_N20-SRF, COWVR, tropics_designed_v1.
20 * Made structure change and bug fix:
21 1. Bug fix for the function CRTM_Compute_SfcOptics_AD in CRTM_SfcOptics.f90
22 2. Change CRTM_MW_Water_SfcOptics.f90 interface variable dimension.
23 3. Remove the channel number in the “all channels” included CRTM coefficient files,
24 e.g. “cris1305_npp” would become simple “cris_npp”.
25 4. Remove “ERRMSG” option in the [DE]ALLOCATE functions to fix an error when using
27 5. Change “Data Statement” to “Array Assignment” in 6 Surface Emissivity modules
28 to fix a compile failure when using -e08 in ifort/16.0.+.
29 6. Add CloudFraction test in check_crtm.fpp.
31 * In this release, there is a new feature for the simulation of all-sky (cloudy)
32 radiance, which utilizes Fortran class function, and now CRTM will support the
33 new compiler with class function, such as ifort version (14.0+, 15.0+, 16.0+),
34 gfortran version (gcc 4.8.5, 4.9, 5.4, 6.4, 7.2), pgi/17.3, ftn/2.3.0.
36 * Compute resource information
38 N/A. This is a library used in the GSI.
