ACCESS-ESM Last Interglacial
The configuration parameters for the Last Interglacial (LIG) should follow the experiment setup in LIG Design.
The configuration for the Last Interglacial Model of ACCESS-ESM is based on the payu version of ACCESS-ESM piControl.
See pre-industrial on how to configure payu.
Differences between piControl and LIG
The differences between piControl and LIG fall in two categories:
Some concentrations are different between piControl and LIG:
These values are set in the payu control directory, under Template:Atmosphere/namelists, with the variable names CO2_MMR, CH4MMR, and N2OMMR, respectively. Since ACCESS-ESM expects these values to be in Mass-Mixing Ratio, the desired values have to be converted from ppm/ppb to MMR.
The path of earth around the sun has changed since the last interglacial, so changes have to be accommodated.
