Summary
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. The model output was prepared for the IPCC Fourth Assessment 20th century experiment (20C3M).

Start from the beginning of the control run (1859 conditions).
Anthropogenic forcings (only) were changed through the run to follow observed values. I.e changes in:
* CO2
* CH4
* N2O
* CFC11
* CFC12
* CFC113
* HCFC22
* Ozone
* Vegetation Distribution
* Sulphur-cycle Emissions
* Soot Emissions
* Biomass Emissions
* Solar variations
* Volcanic aerosols

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:daily 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_DM_hur850

For this experiment 6 ensemble runs were carried out.
But note that the forcings were not the same in all 6. Ensemble members 1-3 had anthropogenic forcings only, members 4-6 had both anthropogenic and natural forcings.

Technical data for this experiment:
This dataset is a composite of UM runs aetkg, aetki and aetkk.
