  1. World Meteorological OrganizationWorking together in weather, climate and water WMO WWW Programme Instruments and Methods of Observation Programme Doc.3.1(4) Cg-XVI (Geneva, 2011) Bertrand Calpini President of CIMO WMO/OBS www.wmo.int Cg-XVI, Doc. 3.1(4)

  2. Revised Terms of Reference for CIMO(Draft Res. 3.1.4/2) WMO Background: • Cg-XV requested to carry out pilot projects (PP) to test the concept of WIGOS. One of them being: « Elaborating the underpinning/cross-cutting role and responsibilities of the Instrument and Methods of Observation Programme » • Carrying out this PP, CIMO consulted with all other Technical Commissions and other Pilot Projects Resulted in: • Improved collaboration with other groups, such as JCOMM and GRUAN • Proposal for revised Terms of Reference for CIMO (see Annex to Draft Resolution 3.1.4/2), responding not only to WIGOS, but to the five priority areas of CIMO Cg-XVI, Doc. 3.1(4)

  3. Revised Terms of Reference for CIMO(Draft Res. 3.1.4/2) WMO Main modifications to ToRs: • Clarification of CIMO role within WIGOS and its collaboration with other TCs and partner organizations • Collaboration with other international organization (ISO, BIPM) on measurement traceability • Interoperability of observing systems Cg-XVI, Doc. 3.1(4)

  4. CIMO priorities for next financial period WMO • Traceability of observations to International System of Units (SI), critical for climate monitoring and in Support/guidance to RICs and NMHSs calibration laboratories • Instrument reliability, compatibility, data quality will be improved through new instrument standards within the WIGOS framework: • Metadata standard, maintenance & site classification standards, standardized instrument performance • User-friendly access to standards • Guidance on new technologies and remote sensing observing systems • Regular update of CIMO Guide, using new Editorial Board, need for a Trust Fund • Collaboration with international standardization organizations, such as ISO and BIPM on the development of standards Cg-XVI, Doc. 3.1(4)

  5. CIMO priorities for next financial period WMO Conduct priority instrument intercomparisons as required by Members, mainly: • Solid precipitation & snow depth • Assessment of instrument performances in various climatic environment (will be conducted on a number of sites ) • Inhomogeneity introduced by automation • Filling one of major gaps in observing practices that is relevant to wide range of user and sectors (Weather, Climate, Hydrology, Cryosphere, …) • Weather Radar algorithms • Assessment of weather radar data quality for the improved QPE • Compatibility of radar output products • Relevant to NWP, disaster risk mitigation, climate studies … Cg-XVI, Doc. 3.1(4)

  6. CIMO priorities for next financial period WMO • Collaboration with CIMO Testbeds and Lead Centres to: • Develop guidance on quality of observations and interoperability of observing systems • Develop guidance on the use and implementation of ground-based remote sensing observing systems • Assess their outcomes and performance • Capacity building through: • Guidance to Members and regular update of CIMO guide as the main source of information for network managers • Technical Conferences (usually 250-300 participants) providing latest developments and expertise with instruments/observing systems and needed interaction with private instrument sector • Dedicated training workshops to fill gaps, especially tuned for developing and least-developed countries Cg-XVI, Doc. 3.1(4)

  7. International Cloud Atlas (WMO-No. 407) WMO New information of interest, not presently mentioned in document: Background: • Available in hardcopy only • Last updated in 1975 (Vol. I, Annex to WMO Tech. Regs.), and 1987 (Vol. II, Plates) • Originally developed by the WMO Commission for Synoptic Meteorology • At present, no Technical Commission/Expert Team is dealing with this document and no funds are available for its update CIMO-Management Group (April 2011) was of opinion that: • Revised electronically available version of International Cloud Atlas would be very valuable to Members • Willing to investigate work needed to revise this document, in collaboration with other interested groups • Complete project likely to last over a number of years and to require significant resources (both human and financial) that would need to be identified Cg-XVI, Doc. 3.1(4)
