The Dynamical Core Model Intercomparison Project (DCMIP) evaluates the fluid flow component of atmospheric General Circulation Models (GCMs). The goal of DCMIP is to survey the advantages and trade-offs of the many numerical and computational design options in the dynamical cores of weather and climate models. These options incorporate the choice of the equation set, numerical schemes, computational grids and their grid staggering options, dissipative mechanisms, and the computational efficiency. In addition, the coupling strategy to physical parameterizations and simple moisture feedbacks are assessed. The assessments utilize a suite of idealized dry and moist dynamical core test cases.
DCMIP is an international effort. We invite the international community of GCM dynamical core model developers and all interested parties to join this virtual community. The virtual DCMIP community will be served by this Commodity Governance (CoG) workspace and its current child projects Dycore-2008 and DCMIP-2012. The workspace hosts a Wiki functionality for lively interactions, links to the DCMIP data sets hosted on the Earth System Grid, metadata, data search functionality, model documents and relevant links to resources. and some basic data analysis and visualization capabilities via a Live Access Server.
