Error: Unable to WGDOS pack to this accuracy

[kqiu]

Hi,

I got an error saying “Unable to WGDOS pack to this accuracy” for Regn1_resb_1_RAL3PS_um_fcst_000 in my u-do621 UM version 13.7 nesting suite. I ran this suite before, and no such error ever occurred. I had a look at the previous ticket, but didn’t find a workable solution there. Could you please help me?

Best,
Kexin

This is usually an indication that the data in the field is corrupt - try running he model without packing the output for the pp0 output stream - that will at least let you see the values of the bad data.

Thanks, Grenville! So set the packing = 0 in my u-do621/app/glm_um/opt/rose-app-lbc.conf?

Hi Grenville,

I had the same error with u-dq917 and tried this solution but didn’t work. I changed packing to 0 but still failed with the same error.

u-dq917 has packing=1 for the pp0 stream - it needs to be set to 0 for the data to no be packed. See here:

Hi Grenville, I changed the packing to 0, and it still failed. I think you only see this because I didn’t commit my change. However, when i tried to fcm commit, it failed and said my suite is not a valid working copy. I am not sure why this happened.

The suite has packing=1 - look in /home/d00/kqiu/cylc-run/u-dq917/work/20181205T0000Z/Regn1_resn_1_RAL3P3_um_fcst_000/rose-app-run.conf which is what the model runs from.

Hi Grenville,

Thanks a lot for your help. Previously, I only changed packing = 0 in ~/cylc-run/u-dq917/app/um/rose-app.conf, after checking /work/20181205T0000Z/Regn1_resn_1_RAL3P3_um_fcst_000/rose-app-run.conf, I then changed the packing there, and everything was working fine afterwards.

Best,
