SciDAC Collaborative Design and Development (2001-2006)
of the Community Climate System Model: Working
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 (email@example.com) and Phil Jones (firstname.lastname@example.org)
are co-PI's for the project and the primary DOE-lab contacts.
Dr. Bob Malone is now PI-emeritis for the project.
Peter Gent from NCAR is the PI of the overall CCSM project.
The LANL COSIM, project
and the LLNL PCMDI, project,
are also DOE OBER funded Climate Change Prediction Projects with close ties
to the CCSM Consortium.
CAUTION: Modelers Working
This project is complete and a final summary report is available

Consoritum wiki .
The project committed to various milestones for 2005. Our Q1 milestone was
to implement a ocean biogeochemistry model that includes the effects of carbon
and sulfur species in the current version of POP (Parallel Ocean Program,
i.e. POP2.0) and further to integrate this version of POP with the CCSM3
to simulate the response of ocean biogeochemistry to climate.
The major milestone for 2005 was to
develop a coupled climate model with an interactive carbon cycle,
a sub model of secondary sulfur aerosols,
and an interactive terrestrial biosphere.
This model will enable studies of the interactions between
the carbon cycle and climate and between secondary sulfur aerosols and climate.
THESE MILESTONES HAVE BEEN MET!
The CCSM development team has produced several documents in support of
an open design process for scientists and software engineers. The public
pages for the Software
Engineering Working Group is collecting these documents.
and progress are being tracked on the chart.
Meeting and teleconference material is linked here
( especially for AG meetings).
Developers associated with this project may apply for accounts on the
National Center for Computational Sciences (NCCS) computers
through the Climate Science End Station allocation and by filling out
the form accounts.
The computational experiments are coordinated through the
NLCF Climate End Station (CES).
The procedure of applying for NCAR code repository access is documented
in Chapter 7 of the CCSM Software Developer's Guide.
An interesting (and helpful) evaluation of software engineering practices
associated with the CCSM before this project began was done by Tom Swain (a professor of SE at
U. Tenn). The report is linked here.
A special issue of the International Journal of High Perfomamnce Computing and Applications on Climate Modeling has come out that details many of the efforts of this project. John Drake, Phil Jones and George Carr were the editors for this special issue.
Thanks to all involved! But especially Dr. Ari Patrinos and Dr. Anjuli Bamzai.
Articles can be viewed online at the link above.
There have been over 200 papers written comparing simulations from all
the climate models submitted to the Fourth Assessment Report of the IPCC.
Many of these are listed at the
IPCC Model Output Page.
