SciDAC Collaborative Design and Development

      of the Community Climate System Model: Milestone for Q4 of 2005

The  Community Climate System Model, is a collaborative effort involving NSF, DOE and NASA aimed at providing US researchers with state of the art coupled climate simulation capabilities.  The DOE national laboratories involved are ANL, LANL, LLNL, LBL, ORNL and PNL.  The National Center for Atmospheric Research and the NASA/Goddard Data Assimilation Office are the primary, non-DOE collaborators.  John Drake ( and Phil Jones ( are co-PIs for the project and the primary contacts.

Implementation of biogeochemical cycles in CCSM has been a high-priority item for DOE Office of Biological and Environmental Research. The Climate Change Prediction Program (CCPP) of the Climate Change Research Division has sponsored this work through the DOE Office of Science SciDAC Program. The software integration effort has been led by Argonne and work has progressed steadily with strong collaboration of the NCAR CCSM Software Engineering Group (CSEG). A document outlining the necessary software engineering and design was written in 4Q04, and the effort resulted in 3Q05 deliverable at which time a complete prototype was run for a five-day smoke test. Progress and the milestones are documented on the project wiki .
