MAIN FOCUS
• Processing and evaluation of key comparison
data
• Completion of the first edition of the CCPRspecific 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.

number
On the importance of SI traceable measurements to monitor climate change
Draft Resolution K
The 23rd General Conference,
recalling Resolution 4 of the 21st General Conference on Weights and
Measures (1999) concerning the need to use SI units in studies of earth
resources, 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 physicochemical measurements of air, ground-based as well as air-borne, and physicochemical 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 the
increasing important role of metrology in studies on global climate change,
recommends relevant bodies to take steps to ensure that all measurements
used to make observations which may be used for climate studies are made
fully traceable to SI units,
and further recommends appropriate funding bodies to support the
development of techniques which can make possible a set of SI-traceable
radiometric standards and instruments to allow such traceability to be
established in terrestrial and space based measurements.
