Metadata for 'IPCC DDC AR4 ECHO-G 20C3M run3'

General Information

Name
IPCC DDC AR4 ECHO-G 20C3M run3
Acronym
ECHO_G_20C3M_3
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 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

Spinup: 6y coupled spinup with ocean restart files from end of year 299 from a preindustrial control run performed at the FUB; the latter sim. initialized with Levitus 94 (oce). Anthropogenic (GHGs, sulfate aerosol direct and first indirect effects) and natural forcing (solar irradiance and volcanic activity implemented through varying solar constant) are used for the 20C3M simulations.

For this experiment there are 5 ensemble runs available.
