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)
