Minutes of the Joint Meeting of the
CCSM Advisory Board
CCSM Scientific Steering Committee
7th Annual CCSM Workshop, 28 June 2002
The Village at Breckenridge, Breckenridge, Colorado
Attendees: Ed Sarachik, Francis Bretherton, Isaac Held, John Drake, Dave Schimel, Max Suarez, Eric Sundquist, Michele Rienecker, Rick Anthes, Maurice Blackmon, Jeff Kiehl, Chris Bretherton, Ping Chang, Jim Hack, Peter Gent, Cecilia Bitz, Danny McKenna, Scott Doney, Steve Meacham, Pam Stevens, Jim Mahoney, Richard Moss, Dave Bader, Phil Merilees, and Lydia Shiver
1. Welcome. Anthes and Sarachik welcomed everyone to the meeting.
2. CCRI. Jim Mahoney, Assistant Secretary of Commerce for Oceans and Atmosphere, stated that Richard Moss (USGCRP) was working on the Climate Change Research Initiative (CCRI) Strategic Plan for the near term (2 to 5 years), and they want to include scientists in the planning process. All plans and documents will be written and open for review and comment. Mahoney stated that basic research is needed, but so is applied research, and minority views will need to be heard.
President Bush's February initiative called for emphasis on science and reporting for the short term, accelerated technical development, accelerated voluntary emissions program, and help for the international community. He consolidated the existing USGCRP and CCRI and stated that this program would be robustly interagency. The Department of Commerce and Department of Energy will co-chair this effort, with all agencies participating including NSF.
The new combined programs will be located at 1700 Pennsylvania Avenue, Washington, DC, with Mahoney staying at NOAA with a small staff. Mahoney is identifying where all the USGCRP funds and all other climate change funding are allocated. He will convene a workshop in Washington, DC in early December to discuss the new plan for this program.
During the question and answer period, Mahoney stated that he recognized the inability of the community to focus dollars on problems due to different focus of each agency and he wants to improve this. He is looking at all the agencies 2004 budgets in depth to help alleviate different agency's focus.
Mahoney also stated that the U.S. should participate in the IPCC and resources will be found to participate.
3. Report on CCSM. Kiehl reported that there were almost 300 participants in this year's CCSM workshop, and the growth is mostly in the U.S. community. The CCSM2 standard model was released to the community on 17 May 2002, which includes model documentation and user's guide and data from the control simulation. The release of the PaleoCCSM, which is one of the most successful applications, is set for July 2002. The CCSM2 simulation shows success in its improved variability and intra-annual to decadal timescales, realistic teleconnection patterns, much improved ocean circulation in both tropics and polar regions, much reduced deep ocean drifts, realistic salinity structure, and much improved sea ice distribution.
Kiehl reported that organizational issues to be worked on were the new CCSM Science Plan that will include science goals, history and process and lessons learned, model development plans, and computational issues. He hopes the new CCSM Plan will be ready for review by the CAB at its next meeting in January. A CCSM Business Plan will also be worked on to identify resources needed and growth areas. He will also improve SSC and working group communications by implementing a SSC/Working Group Co-Chair meeting at the end of the workshop in place of the plenary session and use email and/or conference calls to discuss specific issues. Kiehl stated that a formal closing ceremony of the workshop will need to be devised, and he suggested one page summaries from each working group be posted on the web right away.
The CCSM2 development issues that Kiehl identified were to continue to diagnose and improve aspects of the model, such as the double ITCZ, cold tropical tropopause, and high latitude warm biases; and to try to identify feedback processes in the coupled system that amplify biases through new approaches, such as nudging to observations, use of a slab ocean model, and a rich man's adjoint model.
Kiehl noted future issues for consideration are the role of CCSM in the CCRI, the level of involvement of CCSM in the IPCC FAR, and the continued collaboration between CCSM and GFDL.
Mahoney stated that CCSM's key roles in CCRI are modeling, IPCC involvement, and collaborations continuing with clear mission and priorities, i.e., operations or research.
Mahoney will be invited to the next CAB meeting in Washington, DC.
4. ESMF Update. Suarez updated everyone on this NASA project, which has three parts: a) development of core framework (NCAR lead), b) application codes for climate modeling (MIT and NASA DAO), and c) data assimilation applications. Suarez praised Cecelia DeLuca's leadership of the project.
After the ESMF project is complete, it is hoped that NCAR will maintain the framework that was developed at some level and seek funding to maintain it.
5. DOE Update. Bader reported that there are 3 main infrastructure components at DOE: a) cooperative agreement with UCAR/NCAR for global modeling for climate change projections, b) Climate Change Modeling at Los Alamos, and c) PCMDI. Each is involved in CCSM.
6. GFDL Update and Plans. Held gave a presentation about GFDL's new
model called FMS (flexible modeling system). GFDL has put together development
teams to do research on the global atmosphere, ocean, land, and coupled system.
The GFDL and NCAR atmosphere modelers are comparing the new FMS atmosphere model
and CAM2 in a collaborative project that will extend to other groups within
GFDL and NCAR, such as the ocean modelers.
