Record Label : spinup-1950
Record Title : coupled spinup with fixed 1950s forcings from 1950 initial conditions (with ocean at rest) to provide initial condition for control-1950 and hist-1950
Record identifier : 6131ba78-4cff-11e7-903f-5404a60d96b5
Description : The HighResMIP equivalent of the pre-industrial spinup with fixed 1950s forcing. The forcing consists of greenhouse gases, including ozone and aerosol loading for a 1950s (~10 year mean) climatology. For optimal comparison between models, use of plume aerosol concentrations is recommended (rather than emissions). Initial ocean conditions are taken from the EN4 (Good et al, 2013) ocean analysis over an average period of 1950-1954. This spinup is short compared to DECK (30-50 years for example, to be manageable and consistent across resolutions) to produce initial conditions for control-1950 and hist-1950. At least one ensemble member for each resolution used in the coupled simulations (i.e. standard and high), where high is minimum atmosphere 25-50 km at mod-latitudes and ocean resolution of 0.25 degrees, and a minimum of daily coupling between ocean and atmosphere. Run for 30-50 years.
