IPCC DDC AR4 CCSR-MIROC3.2_(med-res) 20C3M run3

Nozawa, Toru

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 https://www.ipcc-data.org/)
The model output prepared for IPCC Fourth Assessment climate of the 20th Century experiment (20C3M).

These datasets are available in netCDF and GRIB format.
The dataset names are composed of
- centre/model acronym (e.g. MPEH5: Max-Planck-Institute/Echam5)
- scenario acronym (e.g. 20C3M: 20C3M)
- run number (e.g. 1: run 1)
- format identifier (e.g. N: netCDF, G: GRIB)
- variable acronym [with level value] (e.g. hur850: relative humidity, 850 hPa)
--> example: MPEH5_20C3M_1_G_hur850

This run was initiated after 300-year spin-up of the coupled model from an arbitrary chosen initial condition (a snapshot result of a previous version of the model). The preceding spinup was forced by fixed external conditions for the year 1850, including solar and volcanic forcings, GHGs concentration, various aerosols emissions and land use, while all those conditions were changed according to historical data during the 20C in the course of this run.

For this experiment there are 3 ensemble runs available.
