Reformat ACCESS-ESM1.5 CMIP6 output to CRU format for TRENDY #228

Open ccarouge opened 3 months ago

ccarouge commented 3 months ago

As part of developing CABLE configurations using met forcing from ACCESS-ESM1.5 for CMIP6 and ancillary data for ACCESS-ESM1.5, an initial step is to pre-process the CMIP6 output to the CRU format. Then run the TRENDY setup with this data.

Do the time periods match between the historical experiment and TRENDY simulations?

To be honest, it's hard to tell. The meteorological forcing data do not match time periods, with the TRENDY met data spanning 1901-2022 and the ACCESS-ESM1.5 spanning 1850-2014. This isn't to say that the TRENDY runs are run in the quoted time period, the cable.nml implies that the time periods for the TRENDY simulations were 1831-1851. The hidden handling of the time periods in cable_cru_TRENDY.f90 makes it difficult to determine precisely which years of the Met data were actually used, and it varied between experiments.

I am not sure if we still want to do this configuration. We should ask the CABLE4 group.
