ENSEMBLES IPSL-CM4 20C3M run1, daily values

Dufresne, Jean-Louis

20C3M climate simulation ENSEMBLES Stream1 IPCC-AR4 IPSL IPSL-CM4 OPA ORCA05

Summary: These data represent daily values (daily mean, instantaneous daily output, diurnal cycle) 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 20th century simulation(included year 2000) was initiated from the control preindustrial simulation when equilibrium was reached (corresponds to nominal year 1860 of 20C3M). Forcing agents included: CO2,CH4,N2O,O3,CFC11(including other CFCs and HFCs),CFC12; sulfate(Boucher). This is followed by a commitment experiment for the 21th century (year 2001-2100) with all concentrations fixed at their levels of year 2000.

These datasets are available in netCDF format.
The dataset names are composed of
- centre/model acronym (e.g. IPCM4: Institut Pierre Simon Laplace)
- 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: IPCM4_SRA2_1_MM_hur850

For this experiment 1 ensemble run was carried out.
