General Information

ENSEMBLES STREAM2 EGMAM2 20C3M run1, monthly mean values
ENSEMBLES (Production of seasonal to decadal hindcasts and climate change scenarios)
These data represent monthy values (monthly mean, annual cycle) of selected variables for ENSEMBLES (http://www.ensembles-eu.org). The list of output variables can be found in: http://ensembles.wdc-climate.de/output-variables. The model was further developed since ENSEMBLES stream 1 by including a sulfate aerosole transport scheme (Feichter et al, 1997), varying ozone concentrations and land use changes.

The 20th century simulation (1860-2000) is initialized in year 965 of a preindustrial control run (1860 conditions) and forced
with changes of greenhouse gas concentrations (CO2, CH4,
N2O, CFC-11* and CFC-12; time histories of GHGs
concentrations from ENSEMBLES project:
http://www.cnrm.meteo.fr/ensembles/public/data) and
additional solar and volcanic forcing. Additionally, sulphur emissions are used to run a sulfate transport scheme and land use changes are included; land use data from ENSEMBLES project: http://www.cnrm.meteo.fr/ensembles.

The datasets are available in netCDF format.
The dataset names are composed of
- centre/model acronym (FUBEMA: Freie Universitaet Berlin / EGMAM
(=ECHO-G with Middle Atmosphere and Messy))
- scenario acronym (20C3M)
- run number (1: run 1)
- time interval (MM:monthly mean, DM:daily mean, DC:diurnal cycle, 6H:6 hourly, 12h:12hourly)
- variable acronym [with level value] (e.g. hur850: relative humidity, 850 hPa)
--> example: FUBEMA2_20C3M_1_MM_hur850

For this experiment 3 ensemble runs were carried out. NOTE: the forcings were not the same in all 3. Ensemble member 1 had both anthropogenic and natural forcings, members 2-3 had anthropogenic forcings only.

Technical data to this experiment:
The experiment used AGCM MA/ECHAM4 (T30L39) coupled to OGCM HOPE-G (T42 with equator refinement, L20), and was run on a NEC SX-6 (hurrikan.dkrz.de).
