Acronym
NCAR_CCSM3_COMMIT_1
Project(s)
IPCC-DDC_AR4 (IPCC Data Distribution Centre : Assessment Report Four data sets)
Summary
These data represent monthly averaged values of selected variables for the Data Distribution Centre (DDC) of the Intergovernmental Panel on Climate Change (IPCC). (see also http://www.ipcc-data.org/)
The model output prepared for IPCC Fourth Assessment committed climate change experiment (COMMIT).
These datasets are available in netCDF and GRIB format.
For this experiment there are 5 ensemble runs available.
This simulation was initiated from year 2000 of CCSM3 model run b30.030a and executed on hardware bluesky.ucar.edu. The input external forcings are
ozone forcing : mozart.o3.128x64_L18_2000_c040526.nc
aerosol optics : AerosolOptics_c040105.nc
aerosol MMR : AerosolMass_V_128x256_clim_c031022.nc
carbon scaling : carbonscaling_1870-2000_c040225.nc
solar forcing : Fixed at 1366.5 W m-2
GHGs : ghg_1870_2100_c040122.nc
GHG loss rates : noaamisc.r8.nc
volcanic forcing : none
DMS emissions : DMS_emissions_128x256_clim_c040122.nc
oxidants : oxid_128x256_L26_clim_c040112.nc
SOx emissions : SOx_emissions_128x256_L2_1850-2000_c040321.nc
Physical constants used for derived data:
Lv (latent heat of evaporation): 2.501e6 J kg-1
Lf (latent heat of fusion ): 3.337e5 J kg-1
r[h2o] (density of water ): 1000 kg m-3
g2kg (grams to kilograms ): 1000 g kg-1
Integrations were performed by NCAR and CRIEPI with support and facilities provided by NSF, DOE, MEXT and ESC/JAMSTEC.
