Versions of ACCESS-CM 2.0 with the atmosphere resolution reduced
ACCESS-CM 2 N48
A sample of converting an existing ACCESS-CM2 run to N48 resolution is u-bz408. Similar changes could be made to any of the ACCESS-CM 2.0 experiments to run them at N48 resolution.
Consult the diff on Trac for a full list of settings changes
Notable changes to the model are:
- Land mask and land fraction re-generated by interpolating the ocean mask to the atmosphere grid
- Orography remade using CAP
- Enabled default rivstor and rivseq ancillaries
- Other ancillary files regridded to N48
- Oasis weight files replaced
- suite.rc changes to warm starts to allow regridding from N96 runs
Science Changes:
- l_easyaerosol_{lw,sw,zonal} disabled
- l_adjust_theta disabled
- l_skeb2 disabled
- l_ukca disabled
These changes are both for run speed and due to input data needing to be regridded, they can be re-enabled if desired
Ancillary data files were regridded with 'umtool regrid', available in Conda
ACCESS-CM 2.0 Prototype N48
Rose ID: u-ba839
Science Contacts: Chen Li, Dietmar Dommenget
A prototype version of ACCESS-CM 2.0, with the atmosphere resolution reduced to N48L38
A list of changes from the prototype ACCESS-CM 2.0 run is available on MOSRS at https://code.metoffice.gov.uk/trac/roses-u/browser/b/a/8/3/9/trunk/README.md
Data files needed to use the run are stored in $N48_DATA, by default this points to /short/w48/saw562/access2-n48-data
