checksum failure in climate mean

Reported by: s1374103 Owned by: um_support
Component: UKCA Keywords: STASH
Cc: Platform: Monsoon2
UM Version: 8.4


Hi Helpdesk,

I have the following error message regarding a diagnostic s34i447 which is using the a climate meaning profile. I have noticed on other tickets (e.g. that the helpdesk recommends to switch off the problematic diagnostic. However, I need this diagnostic so I can't do that in this instance. Do you have any idea if the problem is related to the diagnostic or how I have defined the time/usage profiles in STASH?

Has a predecessor of this job ever run successfully?

Can you try writing out stash item 34 447 to a non climate mean stream to check if the data is OK?
