Description

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](https://github.com/UKNCSP/CDDS-CMIP7-mappings/issues/355) and [sfpm10_tavg-al-hxy-u](https://github.com/UKNCSP/CDDS-CMIP7-mappings/issues/354).

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.
