These data represent daily values (daily mean, instantaneous output) of selected variables for ENSEMBLES (http://www.ensembles-eu.org). List of output variables: http://ensembles.wdc-climate.de/output-variables. The model output corresponds to the IPCC AR4 "720 ppm stabilization experiment (SRESA1B)". The 21th century sresa2 scenario simulation (2001-2100) is forced with changes of greenhouse gas concentations (CO2, CH4, N2O, CFC-11* and CFC-12), ozone and sulfate aerosols. The datasets are available in netCDF format. The dataset names are composed of - centre/model acronym (INGVSX: Istituto Nazionale di Geofisica e Vulcanologia / SINTEX-G) - scenario acronym (SRESA2) - 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: INGVSX_SRESA2_1_MM_hur850 For model output data in higher temporal resolution and more variables contact Antonella Sanna. Technical data to this experiment: The model, named SINTEX-G (SXG), is an evolution of the SINTEX-F model (Gualdi et al., 2003a, 2003b; Guilyardi et al., 2003, Luo et al. 2004). The ocean component is OPA 8.2 (Madec et al., 1999) with the ORCA2 configuration: 2x2 degrees cos(latitude) with increased meridional resolutions to 0.5 degree near the equator, 31 vertical levels. The evolution of the sea-ice is described by the LIM (Louvain-La-Neuve sea-ice model; Fichefet and Morales Maqueda 1997,1999), which is a thermodynamic-dynamic snow sea-ice model. The atmospheric component is ECHAM4 (Roeckner, 1996) with a T106 horizontal resolution (about 1.125x1.125 degrees) and 19 hybrid sigma-pressure levels. A mass flux scheme (Tiedtke, 1989) is applied for cumulus convection with modifications for penetrative convection according to Nordeng (1994). The coupling information, without flux corrections, is exchanged every 1.5 hours by means of the OASIS 2.4 coupler (Valcke et al.,2000).
