Hi all,
I am trying to use MPI-ESM data to force WRF, so I prepared the surface and pressure grib files and created a new Vtable.
When I run ungrib, I noted that dates are not read correctly; in particular, for each day, ungrib does not find/read the date at midnight (1980-01-02 00:00:00; 1980-01-03 00:00:00;...) although they are present in the GRIBFILEs, as shown below for 3D variables:
File format : GRIB
-1 : Institut Source T Steptype Levels Num Points Num Dtype : Parameter ID
1 : MPIMET unknown v instant 30 1 73728 1 P16 : 11
2 : MPIMET unknown v instant 30 1 73728 1 P16 : 33
3 : MPIMET unknown v instant 30 1 73728 1 P16 : 34
4 : MPIMET unknown v instant 30 1 73728 1 P16 : 52
Grid coordinates :
1 : gaussian : points=73728 (384x192) F96
lon : 0 to 359.0625 by 0.9375 degrees_east circular
lat : -89.28423 to 89.28423 degrees_north
Vertical coordinates :
1 : pressure : levels=30
plev : 3000 to 100000 Pa
Time coordinate : unlimited steps
RefTime = 1980-01-01 00:00:00 Units = days Calendar = proleptic_gregorian
YYYY-MM-DD hh:mm:ss YYYY-MM-DD hh:mm:ss YYYY-MM-DD hh:mm:ss YYYY-MM-DD hh:mm:ss
1980-01-01 00:00:00 1980-01-01 06:00:00 1980-01-01 12:00:00 1980-01-01 18:00:00
1980-01-02 00:00:00 1980-01-02 06:00:00 1980-01-02 12:00:00 1980-01-02 18:00:00
1980-01-03 00:00:00 1980-01-03 06:00:00 1980-01-03 12:00:00 1980-01-03 18:00:00
1980-01-04 00:00:00 1980-01-04 06:00:00 1980-01-04 12:00:00 1980-01-04 18:00:00
I'm not sure if the issue is due to some errors in the grib files or not; however, at the beginning of ungrib.exe the first date (1980-01-01 00:00:00) is read fine, as you can see from the attached ungrib.log.
Any help would be greatly appreciated.
Best,
Alessandro
