1 19/5/2011 B. Calpini CIMO World Meteorological Organization Working together in weather, climate and water Commission for Instruments and Methods of Observation: Report of the President of CIMO WMO/OBSwww.wmo.int WMO Bertrand Calpini President of CIMO Cg-XVI ( Geneva, May 2011)

2 19/5/2011 B. Calpini CIMO Promote: –high quality observational data –world-wide compatibility by: –Defining technical standards, –Testing and calibration –Performing instrument intercomparisons, –Implementing quality control procedures. –Increasing expertise and Capacity-building for: –Improving quality of products and services CIMO mission

3 19/5/2011 B. Calpini CIMO In WMO High Priorities in the Global Framework for Climate Services (GFCS) by improving systematic in situ observations and monitoring of climate in WIGOS by improving the availability, usefulness, quality and utilization of observational data and products of all WMO observing systems (in conjunction with other tech commission such as CBS, JCOMM…)

4 19/5/2011 B. Calpini CIMO (a) Standardization and Intercomparisons; (b) Remote-sensing and New Technologies; (c) Capacity-building. CIMO working structure

5 19/5/2011 B. Calpini CIMO Traceability to SI units By publishing guidance on instrumentation for calibration laboratories By strengthening RICs centers performances by providing an Evaluation Scheme By co-chairing the WMO- BIPM 2010 workshop

6 19/5/2011 B. Calpini CIMO Siting of observing stations QA observations relies also on proper siting and maintenance of instruments. –CIMO-XV approved a siting classification for observing stations –Tool for assessing which station to be used for climate services The CIMO siting classification together with ISO TC 146 to become a common WMO-ISO standard.
