ENSEMBLES STREAM2 METO-HC-HADGEM2AO E1 run1, 6h and 12h instantaneous values

Johns, Tim C.

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 ENSEMBLES Stream 2 experiment.
The model was initialised from the HadGEM2-AO 20C3M run 1 using 1999 conditions.
Anthropogenic forcings (only) were changed through the run to follow values representing the E1 scenario prepared within ENSEMBLES specifically for the Stream 2 experiment, i.e changes in: CO2, CH4, N2O, CFC11, CFC12, CFC113, HCFC22, Ozone, Vegetation Distribution, Sulphur-cycle Emissions, Soot Emissions, Biomass Emissions.
No variations were made to solar radiation and volcanic aerosols.
More information on the E1 scenario on http://ensembles.wdc-climate.de/experiment-list-for-stream-2
The vegetation distribution reflects the commonly-agreed method for including forcing from anthropogenic land use change in ENSEMBLES Stream 2 simulations, in this case using Nathalie de Noblet's maps of future crop and pasture extent derived from the IMAGE2.2 model projections of crop/pasture land use change in the 21st century under E1. These datasets are available in netCDF format.

These datasets are available in netCDF format.
The dataset names are composed of
- centre/model acronym (e.g. METO-HC_HadGEM2AO, for acronym:HADGEM2)
- scenario acronym (e.g. E1: ENSEMBLES 1)
- run number (e.g. 1: run 1)
- time interval (MM:monthly mean, DM:daily mean, D0:daily instantaneous at 0 UTC,6H:6 hourly, 12h:12 hourly)
- variable acronym [with level value] (e.g. hur850: relative humidity, 850 hPa)
--> example: HADGEM2_E1_1_6H_hur850

For this experiment 1 ensemble run was carried out.
