MAIN FOCUS• Processing and evaluation of key comparison

data• Completion of the first edition of the CCPR-

specific guidelines for key comparisons • Consolidation and extension of the service

categories for the CMC database• Evaluation of CMC submissions by the CMC

working group• Formation of a working group on strategic

planning• Winding up the work of the UV working group• Review of the progress in the member

laboratories.

HIGHLIGHTS• Added new Appendix on the treatment of

photobiological quantities (Appendix 3) in the new edition of the SI brochure.

• Signing of a formal working arrangement between the CIPM and the International Commission on Illumination (CIE) in April 2007.

• Appendix 2 of the SI brochure dealing with the practical realization of the definition of the candela was updated.

• Recommendation on global importance of SI traceable measurements to monitor climate change formulated.

On the importance of SI traceable measurements to monitor climate change

Draft Resolution KThe 23rd General Conference,

recalling Resolution 4 of the 21st General Conference on Weights andMeasures (1999) concerning the need to use SI units in studies of earthresources, the environment, human well-being and related issues,

considering• the expansion in the number of international and national initiatives to address the challenges and implications of climate change for the world,• working arrangements between the CIPM and the World Meteorological Organization (WMO),• the increasing importance of optical radiation measurements and physico-chemical measurements of air, ground-based as well as air-borne, and physico-chemical measurements of ocean water, which support research into the understanding of the causes and impacts of climate change,• the importance of basing long-term measurements which relate to climate change on the stable references of the International System of Units (SI),

On the importance of SI traceable measurements to monitor climate change(continued)

welcomes the proposed BIPM/WMO international conference to address theincreasing important role of metrology in studies on global climate change,

recommends relevant bodies to take steps to ensure that all measurementsused to make observations which may be used for climate studies are madefully traceable to SI units,

and further recommends appropriate funding bodies to support thedevelopment of techniques which can make possible a set of SI-traceableradiometric standards and instruments to allow such traceability to beestablished in terrestrial and space based measurements.
