1.5 Experiments: hindcast initialized based on observations and using historical forcing (dcppA-hindcast)

Record Label : dcppA-hindcast

Record Title : hindcast initialized based on observations and using historical forcing

Record identifier : f16dba9a-dd9e-11e6-b89b-ac72891c3257

Description : A coordinated set of multi-member ensembles of retrospective forecasts (hindcasts) initialised each year from 1960 to the present (otherwise every second year). Prescribed CMIP6 historical values of atmospheric composition and/or emissions (and other conditions including volcanic aerosols). Future forcing as the SSP2-4.5 scenario. Run each member for at least 5 years, extend the duration to 10 years with Tier-2 priority. Additional ensemble members for each start date are requested with Tier-3 priority.
