CMIP5
* CMIP [#j1eca607]
CMIP is Coupled Model Intercomparison Project.
CMIP is organized under the World Climate Research Programme (WCRP) the Working Group on Cloupled Modelling (WGCM)
** CMIP3 [#e8f1f973]
Climate model output from simulations of the past, present and future climate was collected by PCMDI mostly during the years 2005 and 2006, and this archived data constitutes phase 3 of the Coupled Model Intercomparison Project (CMIP3).
This unprecedented collection of recent model output is officially known as the "WCRP CMIP3 multi-model dataset."
With the consent of participating climate modelling groups, the WGCM has declared the CMIP3 multi-model dataset open and free for non-commercial purposes. After registering and agreeing to the "terms of use," anyone can now obtain model output via the ESG data portal, ftp, or the OPeNDAP server.
As of July 2009, over 36 terabytes of data
** CMIP5 [#e8f1f973]
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 AR5 as well as others that extend beyond the AR5. CMIP5 is not, however, meant to be comprehensive; it cannot possibly include all the different model intercomparison activities that might be of value, and it is expected that various groups and interested parties will develop additional experiments that might build on and augment the experiments described here.
CMIP5 promotes a standard set of model simulations in order to:
evaluate how realistic the models are in simulating the recent past,
provide projections of future climate change on two time scales, near term (out to about 2035) and long term (out to 2100 and beyond), and
understand some of the factors responsible for differences in model projections, including quantifying some key feedbacks such as those involving clouds and the carbon cycle.
