Modified ERA-Interim data: calc_ecmwf_p.exe warning messages

Post by edougherty » Wed Jun 17, 2020 8:20 pm

Hi all,

I am trying to run WRF with modified ERA-I data (i.e., I added a perturbation to the original data). When I ran WRF using the unmodified ERA-I data, following instructions from https://www.hennohavenga.com/wrf/era-in ... d-era.html, it worked fine, including the calc_ecmwf_p program.

Despite outputting the perturbed ERA-I data in what appears to be the same format as the original (including grib formatting, grib codes, and zaxis types), I get the following error when I run calc_ecmwf_p.exe:

Code: Select all

 WARNING First level is missing!
 WARNING No available level found near level           59 !
This warning appears for all levels (59 down to 2), and at each time. However, the program still outputs 'PRES' files that output GHT, RH, and PRESSURE at each model level (see attached 'PRES' file).

If you could please let me know how to solve this issue with calc_ecmwf_p.exe, I'd appreciate it.

Hi,
To start, you can try running rd_intermediate.exe (found in the utils directory) on the original ERA-I intermediate files and then again on the intermediate files produced from the modified ERA-I data. You can then look for obvious differences in the contents of the two sets of intermediate files.
