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 ocean and sea ice initial states were those of year 100 of a control simulation (CT4) with the same model. Solar, volcanic variability and land use changes are taken into account. Forcing agents included: CO2,CH4,N2O,O3,CFC11(including other CFCs and HFCs),CFC12; sulfate(Boucher),BC,sea salt,desert dust aerosols. These datasets are available in netCDF format. The dataset names are composed of - centre/model acronym (e.g. CNCM3: CNRM/CM3) - scenario acronym (e.g. SRA2: SRES A2) - run number (e.g. 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: CNCM3_SRA2_1_MM_hur850 For this experiment 2 ensemble runs and 4 additional runs (run numbers 3 to 6) were carried out. Technical data to this experiment: CNRM-CM3 (2004): atmosphere: Arpege-Climat v3 (T42L45, cy 22b+); ocean: OPA8.1; sea ice: Gelato 3.10; river routing: TRIP
