CMIP7: Investigate differing level height points between cubes

[mo-laurenboon]

During testing for UKCM2 the following error "Coordinate 'level_height' has different points for the LHS cube '' and RHS cube ''" occurred for the variables mmrpm2p5_tavg-al-hxy-u and sfpm10_tavg-al-hxy-u.

The specific errors for each variable are as follows:

Grid	Variable	Realm	Error Message
mip_convert_ap4_atmos-native	mmrpm2p5_tavg-al-hxy-u	CMIP7_aerosol	Coordinate 'level_height' has different points for the LHS cube 'm01s38i561' and RHS cube 'm01s15i271'.
mip_convert_ap4_atmos-native	sfpm10_tavg-al-hxy-u	CMIP7_aerosol	Coordinate 'level_height' has different points for the LHS cube 'm01s38i560' and RHS cube 'm01s15i271'.

Additionally, in the testing of UKESM1-3-LL, the same errors were encountered for the same variables.

Grid	Variable	Realm	Error Message
mip_convert_ap4_atmos-native	mmrpm2p5_tavg-al-hxy-u	CMIP7_aerosol	Coordinate 'level_height' has different points for the LHS cube 'm01s38i561' and RHS cube 'm01s15i271'.
mip_convert_ap4_atmos-native	sfpm10_tavg-al-hxy-u	CMIP7_aerosol	Coordinate 'level_height' has different points for the LHS cube 'm01s38i560' and RHS cube 'm01s15i271'.

The source of these errors should be investigated and a fix applied to both the UKCM2-0-LL and UKESM1-3-LL models.
