CMIP6 data sources member_id

[ollie-bell]

Just a question about CMIP6 data sources. Please can you explain or point to documentation which explains reasons for ATLAS using a particular member_id for a given source_id and experiment_id?

e.g. why does CMIP6_CESM2_ssp585_r4i1p1f1 use r4i1p1f1 over the other member_id's it has available?

The reason was data availability by the cut-off date. We prioritized members with the maximum number of required variables availably (choosing r1i1p1f1 when there were several in equal conditions).

Ok thanks. Do you know where to find info/documentation describing the differences between member_id's for a given model?
