Dear all,

I downloaded CAMS data from global atmospheric composition forecast for a simulation with WRF-Chem following the instructions How to run the WRF-Chem model using CAMS data as initial and boundary conditions (BC)?#Step4Runningthemodel

The process of downloading the grib data with a python request, converting it to netcdf using the script of section 2.2 of the instructions worked well for 2021-08-01 data. So, I could follow next instructions to finally run mozbc and wrf.exe incorporating successfully BC from CAMS to WRF-Chem.

However, when I downloaded same kind of data for 2022 or 2023 (python request attached before) I got problems converting grib data to netcdf. Specifically running the command  cdo -f nc -b 32 -invertlat   GRG_XXXX.grib   GRG_XXXX.netcdf















I wonder how could I convert grib data to netcdf for NO2, NO, CO, SO2, pan, CH2O CAMS forecast composition chemical species (for 2022 and 2023), obtaining all the parameters with 4 dimensions (time, lev, lat, lon) and the hybrid coordinates hyai, hybi, hyam, hybm in the same output nc file.


Many thanks,


Kind regards,


Maria
