Daily updating SSTs in UM RAS/RNS

Hi @sonyafiddes, @EmmaHoward and @mlipson,

I got u-cj933 to produce a year of sst and sea-ice values over my chosen area.

To do so though I had to produce monthly ERA5 GRIB files with SST/Sea ice for the time period.

I think we could definitely get together to work out shorter time periods if that is something anyone is interested.

We may need to talk about a way this can be set up to be supported.

In the meantime, I have scripts era5grib_parallel based scripts that could be used to produce the monthly ERA5 GRIB files. Please contact me if you would like to get a copy of them. (Or let me know your dates and a regional ancillary suite to run them for).

The daily varying SSTs can then be used by following @Scott’s instructions in this thread UM Nesting Suite - SST ancillary not being used? - #12 by Scott

Please note though that using the daily varying sea-ice values caused my reconfiguration job to crash but the reconfiguration ran successfully if pointing to the climatology (as outlined in Scott’s post).

UPDATE: ran successfully for the 1st level of a double-level nest. Will have to work out how to update the paths for the 2nd level.

I will look into how this could be used to package OSTIA values as well.

Best regards,

@cbengel
