NASA ModelE CMIP5 Climate Simulations

GISS submitted a number of different configurations to the CMIP5 model data repository via the Earth System Grid Federation (ESGF) (or via PCMDI). We have also submitted versions of this model to the ACCMIP project. The configurations vary as a function of the degree of interactivity in the atmospheric composition, the carbon cycle, the ocean model and the atmospheric grid. Each configuration corresponds to a rundeck in the Model E distribution, as follows: GISS-E2-R: ModelE/Russell 2×2.5×L40. This uses the ModelE atmospheric code on a lat-lon grid, with 40 layers in the vertical, a model top at 0.1 mb and is coupled to the Russell ocean model (1×1.25×L32). There are three versions of this model that vary in how aerosols and atmospheric chemistry are handled: physics_version=1 (NINT), aerosols and ozone are read in via pre-computed transient aerosol and ozone fields. The aerosol indirect effect is parameterized. This corresponds to the rundeck E_AR5_NINT_oR.R physics_version=2 (TCAD), aerosols and atmospheric chemistry are calculated online as a function of atmospheric state and tranisent emissions inventories. The aerosol indirect effect is paramterised. This corresponds to the rundeck E_AR5_CAD_oR.R physics_version=3 (TCADI), atmospheric composition is calculated as for physics_version=2, but the aerosol impacts on clouds (and hence the AIE) is calculated. This corresponds to the rundeck E_AR5_CADI_oR.R GISS-E2-H: ModelE/Hycom 2×2.5×L40. This uses the same ModelE atmospheric code as above but is coupled to the HYCOM ocean model (tripolar grid ~1×1×L26 - Note that HYCOM output diagnostics are made available remapped to a cartesian 1x1 grid with a uniform 33 levels). There are also three physics versions as described above. GISS-E2-R-CC: ModelE/Russell 2×2.5×L40. Interactive Carbon Cycle As for GISS-E2-R with interactive terrestrial carbon cycle and oceanic bio-geochemistry. This corresponds to the rundeck E_AR5_NINT_oR_CC.R GISS-E2-H-CC: ModelE/Russell 2×2.5×L40. As for GISS-E2-H with interactive terrestrial carbon cycle and oceanic bio-geochemistry. E_AR5_NINT_oH_CC.R
