| Zusammenfassung |
The UPSCALE (UK on PRACE: weather-resolving Simulations of Climate
for globAL Environmental risk) project constructed and ran an
ensemble of HadGEM3 (Hadley Centre Global Environment Model 3)
atmosphere-only global climate simulations over the period
1985–2011, at resolutions of N512 (25 km), N216
(60 km) and N96 (130 km) as used in current global
weather forecasting, seasonal prediction and climate modelling
respectively. Alongside these present climate simulations
a parallel ensemble looking at extremes of future climate was run,
using a time-slice methodology to consider conditions at the end of
this century.
These simulations were primarily performed using a 144 million core
hour, single year grant of computing time from PRACE (the
Partnership for Advanced Computing in Europe) in 2012, with
additional resources supplied by the Natural Environment Research
Council (NERC) and the Met Office. Almost 400 terabytes of
simulation data were generated on the HERMIT supercomputer at the
High Performance Computing Center Stuttgart (HLRS), and transferred
to the JASMIN super-data cluster provided by the Science and
Technology Facilities Council Centre for Data Archival (STFC CEDA)
for analysis and storage.
In this paper we describe the implementation of the project, present
the technical challenges in terms of optimisation, data output,
transfer and storage that such a project involves and include
details of the model configuration and the composition of the
UPSCALE data set. This data set is available for scientific analysis
to allow assessment of the value of model resolution in both present
and potential future climate conditions. |
