vi ${DIR}/WRF/arch/Config.pl # or Config_new.pl # Change $I_really_want_to_output_grib2_from_WRF = "FALSE" ; # to $I_really_want_to_output_grib2_from_WRF = "TRUE" ; |
5. Install RTTOV (Optional)
Note |
---|
WRFDA 4d-var version 4.5.1 supports up to RTTOV 12.1 |
...

export WRFPLUS_DIR=$(pwd) |
7. Compile WRFDA 4dvar
Copy the source code and go inside the directory
...
Run
ls ./var/build/*.exe | wc -l
to check if 43 executables were successfully compiled.Run
ls ./var/obsproc/src/*.exe
to check ifobsproc.exe
