Discussion
For orbital parameters, include how to set orbital year for those models that have that option.
Another alternative solution for modification of Hudson Bay coastlines might be to allow users to specify some percentage of appropriate land grid squares as lakes.
A vegetation map for 6ka reconstructed from a combination of model output and data analyses would be very useful for modeling groups that will not be using interactive vegetation in their PI and 20th century runs. We could query groups on the best format. For CCSM, a pft vegetation map would be best.
For solar constant, do we want to specify under the PMIP3/CMIP5 “prescribed as in CMIP5 PI”?
CMIP5 CO2 pre-industrial concentrations are 285 ppmv for 1850, 286 ppmv for 1860. HadGEM2ES PI control is getting spun up to 286 ppmv, so I would plan on using 286 for the 6k too.
