On further reflection - this may not be quite right
The models is expecting lbcs each hour (rg01_rs01_m01_lbc_freq=3600s), so for the 12 hr cycle there should be 12 times in the lbc file, but there is only one time.
(does the model interpolate to get hrly lbc updating)
I haven’t changed anything in um_createbc from the default settings, and can’t see whether it does any interpolation in time - do you think it is a matter of adjusting the rg01_rs01_m01_lbc_freq=43200 and CRUN_LEN to match the output frequency of the input era data (i.e. 12 hours)?
I’ve given that a whirl and submitted it, but it hasn’t started running yet…
can you supply ec_cb000 ec_cb012 ec_cb024 ec_cb036 ec_cb048 type files, but at 6hrly intervals?
Unfortunately the ERA5 data I have is only every 12 hours, for December 2000 only. If there’s an alternative 6-hrly source on archer that includes all the fields required to force the model, I could try that…? Do you know if there is another place where era5 sits on disc?
I see that you changed to lbcs each 12 hrs & that produced a more sensible lbc file. We never got to the ancil problem. It might help if you switch off packing - that way there is a chance to see which field is causing problems.
Hi Grenville, I did turn the stashpacking off and am now getting some different errors about the recon. It’s complaining about the topographic index ancils:
[FAIL] namelist:items(7ea74479)=ancilfilename: UM_ANCIL_LSH_TOPIND_DIR: unbound variable
I originally didn’t have these set up to reconfigure because I didn’t think they were necessary but I added them in because initially I was getting this same error in the um_rs01_rg01_fcst step. I noticed this namelist entry file in app/um/opt/rose-app-ra3_pack3.conf so assumed it was necessary for the RA3 config I’m using:
> # #84 land consolidation package
I re-ran the global recon so that the inner domain would pick up the changes from there but am now getting the error in the ec_recon.
I can’t figure out whether this means I should have it in or out, as it seems to complain either way.
