ENSEMBLES INGV SINTEX-G 1PCTTO4X run1, monthly mean values

Gualdi, Silvio

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 model output corresponds to the IPCC AR4 "1%/year CO2 increase experiment (to quadrupling)".

The CO2 quadrupling simulation (1870-2099) is forced with changes of CO2 gas concentation only.

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 (1PTO4X)
- 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_1PTO4X_1_MM_hur850

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).
