These data represent daily values (daily mean, instantaneous daily output) 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 (land use data from ENSEMBLES project: http://www.cnrm.meteo.fr/ensembles). The A1B scenario is the part of the A1 family which describes a balance across all energy sources. The experiment is initialized in year 2000 of the 20C3M_3 run and continues until year 2100 with anthropogenic forcings (CO2, CH4, N2O, CFCs) according to A1B. Additionally, sulphur emissions are used to run a sulfate transport scheme. The datasets are available in netCDF format. The dataset names are composed of - centre/model acronym (FUBEMA2: 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, 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 1 run was carried out. For model output data in higher temporal resolution and more variables contact Janina Koerper. 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).
