Description

Testing for UKESM1-3-LL yielded the following error for variable [land.sweLut.tavg-u-hxy-multi.mon.glb (Emon.sweLut)](https://github.com/UKNCSP/CDDS-CMIP7-mappings/issues/1019):

`CRITICAL: Unable to produce MIP requested variable "sweLut_tavg-u-hxy-multi" for "CMIP7_land": Unsupported axis "landuse". Please contact the MIP Convert core developers (see https://code.metoffice.gov.uk/doc/cdds/mip_convert/support.html)`

In order to be able to produce this variable, a change will either need to be made to the dimensions in the data request information (last updated in v1.2.2) or the axis "landuse" supported by mip convert.

To reproduce this error, please contact myself for the request file. This testing run uses model UKESM1-3-LL (CMIP7), workflow u-dw498 and experiment esm-piControl.

Research direction

Obtain the request file from the issue author and start by tracing mip convert's validation of the "landuse" axis for UKESM1-3-LL. Compare the request dimensions with v1.2.2 and verify the Emon.sweLut variable in workflow u-dw498 can be produced without the unsupported-axis error.
