1.5 Experiments: as piSST with uniform SST increase with magnitude based on abrupt-4xCO2 response (piSST-pxK)

Record Label : piSST-pxK

Record Title : as piSST with uniform SST increase with magnitude based on abrupt-4xCO2 response

Record identifier : f16d76a2-dd9e-11e6-b89b-ac72891c3257

Description : An AGCM experiment with monthly-varying SSTs and sea-ice taken from each model's own piControl simulation (using the 30 years of piControl that are parallel to years 111-140 of its abrupt4xCO2 run) but with a spatially and temporally uniform SST amomaly applied on top of the monthly-varying piSST-control SSTs. The magnitude of the uniform increase is taken from each model's global, climatological annual mean SST change between abrupt4xCO2 and the piControl (using the mean of years 111-140 of abrupt4xCO2, and the parallel 30-year section of piControl). Atmospheric constituents and any other necessary boundary conditions (e.g. vegetation if required) taken from each model's own piControl simulation (using the 30 years of piControl that are parallel to years 111-140 of its abrupt4xCO2 run). Dynamic vegetation should be turned off and the vegetation distribution that is output from the piControl simulation used.

Tier of Experiment : 2

Number of Start Dates : 1

Start year : 1850.0

End year : 1869

Years per Simulation Including all Start Years : 20

Ensemble size : 1

Total number of years : 30

Comment : Same as piSST, but with a spatially and temporally uniform SST anomaly applied on top of the monthly-varying piSST SSTs. The magnitude of the uniform increase is taken from each model's global, climatological annual mean SST change between abrupt4xCO2 minus piControl (using the mean of years 111-140 of abrupt4xCO2, and the parallel 30-year section of piControl)
