| Zusammenfassung |
| The scientific understanding of the Earth's climate system, including the
central question of how the climate system is likely to respond to
human-induced perturbations, is comprehensively captured in GCMs and Earth
System Models (ESM). Diagnosing the simulated climate response, and
comparing responses across different models, is crucially dependent on
transparent assumptions of how the GCM/ESM has been driven – especially
because the implementation can involve subjective decisions and may differ
between modelling groups performing the same experiment. This paper outlines
the climate forcings and setup of the Met Office Hadley Centre ESM,
HadGEM2-ES for the CMIP5 set of centennial experiments. We document the
prescribed greenhouse gas concentrations, aerosol precursors, stratospheric
and tropospheric ozone assumptions, as well as implementation of land-use
change and natural forcings for the HadGEM2-ES historical and future
experiments following the Representative Concentration Pathways. In
addition, we provide details of how HadGEM2-ES ensemble members were
initialised from the control run and how the palaeoclimate and AMIP
experiments, as well as the "emission-driven" RCP experiments were
performed. |
