Name
IPCC DDC AR4 NCAR-PCM SRESA1B run1
Acronym
NCAR_PCM_SRESA1B_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 SRES A1B experiment.
For this experiment there are 4 ensemble runs available.
This simulation was initiated from year 1980-03 of PCM1 model run B06.08 and executed on hardware cheetah.ccs.ornl.gov. The input external forcings are:
"ozone forcing : noaao3.122yr.IPCC.041299.nc,
"solar forcing : Hoyt/Schatten solar forcing, defined in code,
" : see website for details,
"GHGs : defined in code, see website,
"volcanic forcing : none,
"SOx emissions : SO4-A1.1980-2099.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
