Revision as of 23:25, 29 April 2021
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.
Contents
Getting Started
The UM is configured through a graphical interface, which is run from the server Accessdev. Follow the Set Up Instructions for the version of the model you want to run.
There are two ways to run the model. Newer versions (post UM 10) use Rose & Cylc, older versions (pre UM 10) use a program called UMUI.
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 climate_help@nci.org.au to request an account on the Met Office server.
