ENSEMBLES BCCR-BCM2.0 20C3M run1, 6h and 12h instantaneous values

Drange, Helge

These data represent 6 hourly and 12 hourly instantaneous 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

This experiment was initiated from model year 235 (nominal year 2000) of the climate of the 20th Century experiment (with bcm_experiment_name: PT3) Varying forcing agents: CO2,CH4,N2O,CFC11(including other CFCsand HFCs),CFC12 and sulfate aerosols (Boucher data, only direct effect).
Non-varying forcing agents: Background aerosols: black carbon,sea salt,desert dust, stratospheric and tropospheric ozone, solar irradiance (1368 W/m2) and the distribution of land cover types. No volcanic aerosols. No heat or fresh water adjustments.

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. 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: MPEH5_SRA2_1_MM_hur850

For this experiment 1 ensemble run was carried out.
