Vn11.1 nudging with Strat-Trop - 634 stash request

1

Hi,

I am trying to get an vn11.1 nudged job to work on Archer2 (u-dw863) with Strat-Trop. It is a copy -f u-be303/archer2 with no other changes except the get nudging working following Nudged UKESM1-AMIP - UKCA

It fails on recon with the message below. I believe 634 is surface wetness but my understanding was that it was introduced a later UM version so I am confused as to why it is being requested here.

Could there be an old nudging field with entry 634 which is needed?

Many thanks for your help,

Hi James,

It looks like the run is being initialised with a restart dump from u-df184, which is a UM13.3 configuration. This will include new prognostics added after 11.1 which your run cannot recognise.

If a suitable UM11.1 compatible dump is not available then you could try to remove this (and any other new prognostic) using the Mule library: e.g. Examples: Filtering — Mule API documentation ( using only field.lbuser4 == 634 as a filter).

Of course, thanks Mohit, I’ll find a vn11.1 dump
