ENSEMBLES STREAM2 METO-HC-HADGEM2AO SRA1B run2, daily values

Johns, Tim C.

ENSEMBLES Stream2 HADGEM2 Hadley-Centre SRES-A1B UKMO

Summary: These data represent instantaneous daily values and daily mean 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 and comprises the HadGEM2-AO run ahnde
(1/12/1999-1/01/2100). 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 SRES A1B scenario from the IPCC Fourth Assessment, 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. Most of the forcings were identical to the
equivalent HadGEM1 A1B run with the exception of the vegetation distribution which was
modified to reflect 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 A1B. The output
datasets are available in netCDF format. The dataset names are composed of: -
centre/model acronym (METO-HC_HadGEM2AO); scenario acronym (e.g. SRA1B: SRES A1B); run
number (e.g. 1: run 1); time sampling abbreviation (MM: monthly mean, DM: daily mean,
D0: daily instantaneous at 0 UTC, 12H: 12-hourly instantaneous, 6H: 6-hourly
instantaneous); variable acronym [with level value] (e.g. hur850: relative humidity,
850 hPa) --> example: METO-HC_HadGEM2AO_20C3M_1_6H_hur850. For this experiment 2
ensemble runs were carried out (data relating to aerosol variables are only available
from this second ensemble member).
