NOAA Council on Long-Term Climate Monitoring (CLTCM) Presentation to NOAA Science Advisory Board November 5 – 7, 2002 Chair: Tom Karl Executive Secretary: Chris Miller Reporter: Bill Murray 1

The NOAA Council on Long-Term Climate Monitoring (CLTCM) Terms of Reference Purpose of the CLTCM:  Evaluate and prioritize requirements for existing and planned climate-related observing systems including data processing and data management related to trends and variability  Consider practices/systems that span the range of atmospheric, oceanographic, terrestrial, and cryospheric variables, with attention to issues of accuracy, biases, and errors: - forcings (solar, GHGs, aerosols...) - feedbacks (sea ice, land cover, snow cover, water vapor, clouds…) - responses (atmospheric temperature, precipitation, ecosystems…)  Report findings to NOAA management, i.e., provide advice and recommendations for remedial action and initiatives 2

CLTCM Membership  Reconstructed during Summer/Fall 2002  Membership Invitation Acceptances Received (As of October 10, 2002) Tom Karl (Chair), NOAA National Climatic Data Center Mark Abbott, Oregon State University Antonio J.

NOAA Science Advisory Board Council on Long-Term Climate Monitoring NESDIS Board of Directors NOAA Climate and Global Change Panel Climate Observation and Services Board formal reporting requirement and approval provide Council reports as advice 5

Council Operation (1)Meet semiannually or as appropriate to evaluate the status of current and proposed climate observing and/or data management systems (2)Develop advice or recommendations regarding monitoring activities, development of new initiatives, observing system priorities, national data management and archive priorities, budget implications or other issues pertinent to ensuring high quality climate monitoring (3)Report to the SAB at least annually, bringing a broad view of national and international climate and global change research activities and their implications for monitoring requirements and providing the advice or recommendations which the Council would like the SAB to critically review and forward (4)Inform NOAA of opportunities and roles to interact constructively with other agencies or institutions in promoting high quality climate monitoring (5)Report to the NOAA SAB and inform/collaborate with the Climate and Global Change Panel, the NESDIS Board of Directors, and the NOAA Climate Observations and Services Board as appropriate 6
