Model Simulations

Experiment: tcrpb

Famous 4.5.3 deglaciation 21k-20k run on babybluecrystal. Land-sea mask is constructed from ice-5g. Orital forcing and ghg concentrations (CO2, CH4, and N2O) are set to 21.0k values (according to PMIP2). CFC 0, O3 has 3 prescribed modern (not pre-industrial) values are 12 ppbv for the troposphere, 120 ppbv for the tropopause and 900 ppbv for the stratosphere. Freashwater fluxes consist of the modern ice calving flux. The run is initialised with modern values for terrestrial variables and albedo. soil moisture and soil temp are from 21.0k (tcnvb). These are extrapolated onto the new land points. Run starts from a 21k equilibrium run tcole (1000 years long). This is not an accelerated run, job length is 200 yrs.

FAMOUS_4.5.3_21k_PMIP_bigblue	Famous 4.5.3, 21.0k. PMIP2 set up, Ice5g topog, land-sea mask and ice-sheet, PMIP GHG values and higher ocean salinity. Should be the LGM control run for the tuning of FAMOUS. This is a copy of tcmul but run on bigblue.
