Hi CMS, Am currently writing an app to calculate integrated vapour transport online and need first to extract fields from pp and save to netcdf. I was hoping to do this with convsh, but i couldn’t find out if there is already an install on archer2 - if so, can you point me towards it please? Cheer…

Ella Why not use cf-python? Grenville

Ooh, didn’t know I could… is there a guide to using it anywhere? I need to stashsplit my data into individual .nc files, basically.

on ARCHER2: export PATH=/home/n02/n02/dch/cf/bin:$PATH export PYTHONPATH=/home/n02/n02/dch/cfdm:/home/n02/n02/dch/cf-python:$PYTHONPATH then have a look at: https://ncas-cms.github.io/cf-python/tutorial.html https://ncas-cms.github.io/cf-python/tutorial.html#sorting-and-selecting-from-field-lists…

Thanks for this Grenville. Am using cf in a new app (calc_IVT) which creates .nc files from UM model level variables (u,v,q,P) in pp files, then calculates integrated water vapour transport online using CDO, and then delete the full profiles that I don’t need before I archive to jasmin. I think I’v…

Tried adding ‘module load netcdf4’ to the env-script, pre-script and main.sh but still doesn’t seem to want to work. I also get the same error if I try to run create_IVT_vars.py directly from the archer command line. Is the cf-python install overwriting the call to load netcdf4 or something? Trace…

pl give us read permission on /work/n02/n02/shakka/create_IVT_vars.py

Done. Have also give permissions on calc_IVT.sh.

Ella - this looks like an environment problem – remove from your .bashrc export PATH="/home/n02/n02/shakka/.local/bin:$PATH" and possibly export PATH="/work/n02/n02/shakka/:$PATH" there is no need to module load netcdf4 (that was a mistake on my part) Grenville

I think those lines are the ones you suggested I add to my .bashrc to allow the get_era_data app (esp cdsapi) to work - will removing this interfere with that?

Install of convsh on archer2?
