ENSEMBLES BCCR-BCM2.0 SRESA1B run1, daily values

Drange, Helge

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 model output was prepared for the IPCC Fourth Assessment SRES A1B experiment.

The A1B scenario is the part of the A1 family which describes a balance across all energy sources. The experiment has been initialized in year 2000 of the 20C_1 run and continues until year 2100 with anthropogenic forcings (CO2, CH4, N2O, CFCs, O3 and sulfate) according to A1B.

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. SRA1B: SRES A1B)
- 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_SRA1B_1_MM_hur850

For this experiment 1 ensemble run was carried out.
