These data represent daily values (daily mean, instantaneous daily output, diurnal 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 output was prepared for the IPCC Fourth Assessment climate of the 20th Century experiment (20C3M). The 20th century simulation (1860-2000) is initialized in year 157 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 (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: FUBEMA_20C3M_1_MM_hur850 For this experiment 3 ensemble runs were carried out. For model output data in higher temporal resolution and more variables contact Falk Niehoerster. 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).
