IPCC Working Group I AR5 snapshot: The additional historical experiments (historicalExt/GHG/Misc/Nat)

"historicalXXX" are an experiment family of additional historical experiments of the CMIP5 - Coupled Model Intercomparison Project Phase 5 ( https://pcmdi.llnl.gov/mips/cmip 5 ) including historicalExt, historicalGHG, historicalMisc and historicalNat. CMIP5 is meant to provide a framework for coordinated climate change experiments for the next five years and thus includes simulations for assessment in the IPCC AR5. This subset of the CMIP5 additional historical data were collected by ETH Zurich until 15th March 2013 in support of IPCC AR5 Working Group 1 ( http://wiki.c2sm.ethz.ch/COSMO/CMIP 5 ). These data are part of the IPCC-DDC AR5.


historicalXXX: Variation of the CMIP5 historical experiment with alternate forcing (only greenhouse gas forcing for GHG and only natural forcing for Nat) or an extended historical run until near-present (Ext).
