Dear GSI help,
I recently updated from GSI v3.6 to GSI v3.7 for data assimilation with a regional WRF model implementation and did some tests with 3dvar. Unfortunately, my old scripts that used to work for assimilating radiance data are not functioning well with v3.7. Specifically, I am not able to assimilate the AIRS-AQUA infrared radiance. I am listing the key setting below. Could you please point to me what went wrong in my set-up?
Script for running 3dvar:
srcobsfile[7]=${OBS_ROOT}/gdas.t${HH}z.airsev.tm00.bufr_d (NOTE: this is the test gdas airsev buff data)
gsiobsfile[7]=airsbufr
# NOTE: I noticed the CRTM SpcCoeff.bin and TauCoeff.bin file names have changed, so I linked these two files to different names.
ln -sf ${CRTM_ROOT_ORDER}/airs281_aqua.SpcCoeff.bin ./airs_aqua.SpcCoeff.bin
ln -s f ${CRTM_ROOT_ORDER}/airs281_aqua.TauCoeff.bin ./airs_aqua.TauCoeff.bin
ln -sf ${CRTM_ROOT_ORDER}/airs281_aqua.SpcCoeff.bin ./airs281SUBSET_aqua.SpcCoeff.bin
ln -sf ${CRTM_ROOT_ORDER}/airs281_aqua.TauCoeff.bin ./airs281SUBSET_aqua.TauCoeff.bin
ln -sf ${CRTM_ROOT_ORDER}/airs281_aqua.SpcCoeff.bin ./airs281_aqua.SpcCoeff.bin
ln -sf ${CRTM_ROOT_ORDER}/airs281_aqua.TauCoeff.bin ./airs281_aqua.TauCoeff.bin
Namelist:
airsbufr airs aqua airs281SUBSET_aqua 20.0 2 0
airsbufr airs aqua airs281_aqua 20.0 2 0
airsbufr airs aqua airs_aqua 20.0 2 0

Thank you so much in advance for your time.
