Hello everyone
I have a problem running my WRFDA 3Dvar case.
I compiled WRFDA based on WRF 4.4.2 and RTTOV 12.1.
I attempted to run 3DVAR with IASI BUFR data obtained from NCEP GDAS Satellite Data(NCAR RDA Dataset ds735.0).
However, the 3DVAR process stopped at rttov_checkinput.F90 with this WRFDA version, RTTOV, and IASI data.
In rsl.error.0000, the reason da_wrfvar.exe stopped was the invalid zenith angle.
Interestingly, when I tried to run da_wrfvar.exe with CRTM, data assimilation worked.
Do I need to pre-process radiance data before running da_wrfvar.exe?
Or is it not possible to use IASI BUFR data with RTTOV?
I would appreciate any ideas on how to solve this problem.
Best regards
