ENSEMBLES EGMAM 20C3M run3, monthly mean values

Niehörster, Falk

These data represent monthly averaged values 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 output corresponds to the IPCC AR4 "climate of the 20th Century experiment (20C3M)".
The 20th century simulation (1860-2000) is initialized in year 207 of the preindustrial control run (1860 conditions) and forced with changes of greenhouse gas concentartions (CO2, CH4, N2O, CFC-11* and CFC-12; time histories of GHGs concentrations from ENSEMBLES project: http://www.cnrm.meteo.fr/ensembles/public/data).
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 (3: run 3)
- 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: FUBEMA_20C3M_3_MM_hur850
For this experiment 3 ensemble runs were carried out.
