Which ECMWF data set / file / version to use? #91

Hello,

I'd like to know which ECMWF data to download for NWP_FLAG = 1. Do you have a sample MARS request?

simonrp84 commented 6 months ago

Hi Pierre, see the attached zip for two scripts I've previously used for retrieving ERA5 data from MARS for use with NWP_FLAG = 1. Bear in mind this script is a little bit old (and itself a derivative of one supplied by the NWC-SAF) so it will probably require some updates before it runs.

ERA.zip

Also, looking at the script itself I suspect it may be for retrieving data from the operational forecast stream rather than ERA5 ;-) But that should be easy to fix.

Thanks a lot for the support @simonrp84 :-) Will test this soon!

pdebuyl commented 6 months ago

If that is useful to anyone, I put it together as a single python file. I had to change the parameter numeric values. I put the filename that ORAC expects from me as far as I can understand. get_ecmwcf_netcdf_for_orac.py.gz

pdebuyl commented 6 months ago

Call as python get_ecmwcf_netcdf_for_orac.py 2023-08-25 00 for instance.

Closing, this is addressed.

Sorry, this slipped my mind in the rather hectic last month! Glad you found the data in the end!
