The Ocean-Carbon Cycle Model Intercomparison Project (OCMIP) is a research initiative of the Global Analysis, Interpretation, and Modeling (GAIM) Task Force of the International Geosphere-Biosphere Program (IGBP). During its second phase, OCMIP provides a crucial link between IGBP/GAIM and IGBP/JGOFS (Joint Global Ocean Flux Study).


To improve the predictive capacity and speed the development of global-scale, three-dimensional, ocean carbon-cycle models through standardized Model evaluation, sometimes called validation, refers to comparison of model predictions with data. Model intercomparison is useful where data are available because a group effort accelerates the repetitive loop of model development, evaluation, and reformulation. Model intercomparison also allows research to focus on important regions where data is sparse, particularly where models differ substantially. Through model intercomparsion important differences between models can be identified and their causes found. Regarding predictions, model intercomparison provides more information concerning uncertainties than would a single model simulation.
