These data represent 6 hourly and 12 hourly instantaneous 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 This experiment was initiated from model year 235 (nominal year 2000) of the climate of the 20th Century experiment (with bcm_experiment_name: PT3) Varying forcing agents: CO2,CH4,N2O,CFC11(including other CFCsand HFCs),CFC12 and sulfate aerosols (Boucher data, only direct effect). Non-varying forcing agents: Background aerosols: black carbon,sea salt,desert dust, stratospheric and tropospheric ozone, solar irradiance (1368 W/m2) and the distribution of land cover types. No volcanic aerosols. No heat or fresh water adjustments. These datasets are available in netCDF format. The dataset names are composed of - centre/model acronym (e.g. MPEH5: Max-Planck-Institute/Echam5) - 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: MPEH5_SRA2_1_MM_hur850 For this experiment 1 ensemble run was carried out. Technical data to this experiment: BCM2.0, (2005): atmosphere : ARPEGE V3 T63L31 (cy 22b+) ocean : NERSC-MICOM V1.0 (based on MICOM V2.8), 35 vertical layers, 1.5(E-W) X 0.5(N-S) deg. res. near equator with gradual transformation to square grid cells away from equator sea ice : NERSC Sea Ice Model (Viscous-plastic + thermodynamic), 4 gridcells per ocean grid cell land : ISBA ARPEGE V3 version The output from the model run: tre.ii.uib.no:/net/bcmhsm/nilsg/BCM
