Global Atmosphere
Global Atmosphere (GA) is the name of the UK Met Office's resolution independent global configuration of the Unified Model
It is normally paired with a Global Land (GL) configuration of the JULES land-surface model
It may also be coupled with the NEMO ocean and CICE sea ice models to form the Global Coupled (GC) coupled model (the basis of ACCESS-S)
Met Office documentation of the configuration can be found on the GMED (Global Model Development) website (Requires a MOSRS account)
The configuration is versioned separately from the model code, so you can run a GA 7 job using UM versions from 10.3 to 11.4
GA jobs are run using Rose-Cylc
Experiments on Gadi
These jobs are based off official Met Office releases, ported to NCI
