The Unified Model is the atmospheric component of ACCESS, developed by the UK's Met Office. The Centre of Excellence sublicences the UM from CAWCR, our licence allows us to run the UM at NCI only. To run the UM you will first need an NCI account, then ask for connection to the ACCESS group through NCI's account website.
The ACCESS climate models are based on version 7.3 of the UM, most Australian university research uses this version. The Bureau makes use of the more recent version 7.8 for forecasting, and is evaluating moving to version 8.2. These are the primary versions supported at NCI, other versions are available but may not be quite as well tested. Different versions include changed science configurations, for details see the release notes.
The Met Office have a tutorial for the model at https://code.metoffice.gov.uk/doc/um/latest/
UM 10 / Global Atmosphere / ACCESS 2.x
The current version of the Unified Model is available from the Met Office's repository site https://code.metoffice.gov.uk.
ARCCSS researchers need to email firstname.lastname@example.org to request an account on the Met Office server.

If a run fails, search for 'UM ERROR' in the .leave file to see what went wrong. Common issues are listed here
- Using STASH
- UM output filename convention
- Analysing UM outputs & Converting to NetCDF
- Archiving Output
- Comparing UM Files
- Mapping UM outputs to CMIP fields
