Coupled model intercomparison project
Encyclopedia
In climatology
, the Coupled Model Intercomparison Project (CMIP) is the analog of AMIP
for global coupled ocean-atmosphere general circulation models. CMIP began in 1995 under the auspices of the Working Group on Coupled Modeling (WGCM), which is in turn under auspices of CLIVAR
and the Joint Scientific Committee for the World Climate Research Program. The Program for Climate Model Diagnosis and Intercomparison at Lawrence Livermore National Laboratory
supports CMIP by helping WGCM to determine the scope of the project, by maintaining the project's data base, and by participating in data analysis. CMIP has received model output from the pre-industrial climate simulations ("control runs") and 1% per year increasing-CO2 simulations of about 30 coupled GCMs. More recent phases of the project (20C3M, ...) include more realistic scenarios of climate forcing.
The current phase of the project (as of 2010) is CMIP5.
CMIP5 will include more metadata
describing model simulations than previous phases. The METAFOR
project has created an exhaustive schema
describing the scientific, technical, and numerical aspects of CMIP runs and this information will be
archived along with the output data.

CLIVAR is a component of the World Climate Research Programme. Its purpose is to describe and understand climate variability and predictability on seasonal to centennial time-scales, identify the physical processes responsible for climate change and develop modeling and predictive capabilities for...

Metadata
The term metadata is an ambiguous term which is used for two fundamentally different concepts . Although the expression "data about data" is often used, it does not apply to both in the same way. Structural metadata, the design and specification of data structures, cannot be about data, because at...
