Ungribbing ds113.1 with WPS

Hi,

I'm trying to ungrib my ds113.1, which I downloaded from the NCAR website. I was aware of the record length of the grib message, so I added

&ungrib
ec_rec_len = 26214508

to my namelist. However, now when trying to ungrib, I get an error that the data is not found. I attached the ungrib.log, to see the total process/error. I also attached my namelist and a screenshot of my downloaded files.

I linked my Vtable to Vtable_ECMWF and I know for sure that I correctly linked my datafiles.

Can someone help me?

Hi,
Looking at your ungrib.log, it looks like it was able to find the GRIBFILE.* files in your WPS directory, but it doesn't look like it's actually finding any data matching the codes in the Vtable you're using. For e.g.,

Code:
2024-04-03 12:53:59.310 --- Inventory for date =
2024-04-03 12:53:59.315 ---      PRES     GEOPT       HGT        TT        UU        VV        RH     DEWPT   LANDSEA   SOILGEO   SOILHGT      PSFC      PMSL  SKINTEMP    SEAICE       SST   SNOW_EC      SNOW  ST000007  ST007028  ST028100  ST100289  SM000007  SM007028  SM028100  SM100289
2024-04-03 12:53:59.315 --- -------------------------------------------------
2024-04-03 12:53:59.315 --- -------------------------------------------------

If ungrib finds data that match the gribbed codes, it will show an X under each variable, and there is nothing here. Furthermore, in the g1print output you've shown above, the file on which you performed that is only showing a single variable with codes 15, 1, 0, 0, which doesn't match any of the codes in Vtable.ECMWF.

Make sure that you are obtaining files for all the mandatory fields. If you need help, contact the RDA CISL support group and they should be able to assist you.
