ENSEMBLES IPSL-CM4 SRESB1 run1, daily values

Dufresne, Jean-Louis

These data represent daily values (daily mean, instantaneous daily output) 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 was prepared for the IPCC Fourth Assessment 550 ppm stabilization experiment (SRES B1).

The B1 scenario describes a storyline with rapid change in economic structures toward a service and information economy, with reductions in material intensity and the introduction of clean and resource-efficient technologies. The experiment has been initialized in year 2000 of the 20C_1 run and continues until year 2100 with anthropogenic forcings included: CO2,CH4,N2O,O3,CFC11(including other CFCs and HFCs),CFC12; sulfate(Boucher) according to A2. The experiment is extended until year 2300 with all concentrations fixed at their levels of year 2100 (stabilization experiment).

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.
