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
