ds113.1 Ungrib "Error: Data not found" using WPS 4.3.1


New member

I downloaded data from of the ds113.1 dataset and im trying to preprocess it using WPS 4.3.1. In theory, this datset is supported since 4.0.

When i try to use ungrib.exe with the ECMWF Vtable shows this error:

Subroutine DATINT: Interpolating 3-d files to fill in any missing data...
Looking for data at time 2021-12-07_00
ERROR: Data not found: 2021-12-07_00:00:00.0000

I checked that the dates are correct, try different hours and redownload the data but still the same.

On the namelist file i put the option "ec_rec_len = 26214508" because i had an error. (ERROR: Grib2 file or date problem, stopping in edition_num.)

Thank you for your time.

I believe the issue you're seeing is because the dates are out of order for the fields you are downloading. If I look at your "ds113.1 files downloaded.txt" file, it shows, for e.g.,


which you can see the dates go back and forth between the 6th, 7th, and 8th. I'm not sure why the fields are given in this way, and we've seen an increase in issues with this from other users (you can find other conversations on the forum if you search a bit in the WPS section). Unfortunately you will need to find a way to ensure the data are arranged in the correct order within in each file. You may be able to contact the group who manages the data to ask for their assistance. If you find a useful method, please let us know so we can assist other users with this in the future!
