General Information

Name
IPCC DDC AR4 NCAR-CCSM3 SRESA1B run1
Acronym
NCAR_CCSM3_SRESA1B_1
Project
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 SRES A1B experiment.
For this experiment there are 7 ensemble runs available.

This simulation was initiated from year 2000 of, CCSM3 model run b30.030a and executed on, hardware cheetah.ccs.ornl.gov. The input external forcings are,
"ozone forcing : A1B.ozone.128x64_L18_1991-2100_c040528.nc,
"aerosol optics : AerosolOptics_c040105.nc,
"aerosol MMR : AerosolMass_V_128x256_clim_c031022.nc,
"carbon scaling : carbonscaling_A1B_1990-2100_c040609.nc,
"solar forcing : Fixed at 1366.5 W m-2,
"GHGs : ghg_ipcc_A1B_1870-2100_c040521.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_A1B_128x256_L2_1990-2100_c040608.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.
