ACCESS-ESM1.5-CM2 differences affecting input
ACCESS-ESM1.5 and ACCESS-CM2 differ in many ways that are relevant to input file formats, contents and processing.
UM differences
Differences in aerosol scheme
See MOSRS GA ticket #60 and especially the ticket details and full ticket details. To allow for the development of the UKESM model, between UM vn8.6 and UM vn10.2 the UM aerosol scheme was changed from the CLASSIC aerosol scheme to the GLOMAP-mode UKCA aerosol scheme. This affected many stash codes and ancillary files. Consequently, the aerosol-related ancillary files for ACCESS-ESM1.5 (UM vn7.3) and ACCESS-CM2 (UM vn10.6, GA7.1) for each of the same CMIP6 forcings are completely different.

None of these CM2 STASH codes correspond to the ESM1.5 STASH codes above.
The CLASSIC Aerosol Scheme
Lateral Boundary Conditions (not relevant for global models?)
UMDP 020 Table 2 defines STASH codes in section 31 for Lateral Boundary Conditions corresponding to the CLASSIC tracers. These correspond to the publicly listed STASH codes.
Iris includes these STASH codes in the STASH_TRANS dictionary but not in the STASH_TO_CF dictionary.
None of these STASH codes correspond to either the ESM1.5 or the CM2 codes listed here.
