Atmospheric Model Intercomparison Project

Project Description
The Atmospheric Model Intercomparison Project (AMIP) is conducted in
association with the The Program for Climate Model Diagnosis and
Intercomparison (PCMDI) project. Some 30 AMIP modeling groups are
simulating the climate of the decade 1979-1988 using the observed
monthly sea-surface temperature and sea ice, as well as common values
of solar luminosity (1365 W/m^2) and atmospheric carbon dioxide
concentration (345 ppm). The participating models' principal
numerical algorithms and dynamical/ physical parameterizations are
summarized in AMIP model documentation.
A set of monthly-mean standard output data from each AMIP model is
archived at PCMDI. Some AMIP modeling groups have also provided
history data at six-hourly intervals. Analysis of the models'
performance in comparison with observational data reveals their
systematic errors, while comparison of the AMIP simulations with each
other provides a measure of current modeling uncertainties.
More AMIP information is located on the World Wide Web.
