8 WMO 8 Currents Status More global ocean observations

9 WMO 9 Current Status Expansion in free data sets

10 WMO 10 Current Status Climate-gate

11 WMO 11 Proper Data Management More than just placing a meteorological, oceanographic or geophysical instrument in the water or on the land, More that just collecting an observation, and More than just disseminating the data via a data portal

12 WMO 12 WMO Strategic Thrusts 1.Strategic Thrust – Improving Service Quality and Service Delivery 2. Organization-Wide Expected Results – Enhanced capabilities of Members to deliver and improve access to high quality weather, climate and water and related environmental predictions, information and services in response to users needs and to enable their use in decision-making by all relevant societal sectors.

13 WMO 13 Conclusion Any and all atmospheric, oceanographic and geophysical observations will be considered as a climate or high-quality observations – and should be treated as such.

14 WMO 14 GCOS Climate Monitoring Principles 1.Assess impact of new systems or changes to existing systems prior to implementation. 2.Ensure a suitable period of overlap for new and old observing systems. 3.The details and history of local conditions, instruments, operating procedures, data processing algorithms and other factors pertinent to interpreting data (i.e., metadata) should be documented and treated with the same care as the data themselves. 4.Regularly assess quality and homogeneity of data as a part of routine operations. 5.Integrate into national, regional and global observing priorities the needs for environmental and climate-monitoring products and assessments, such as IPCC assessments. 6.Maintain operation of historically-uninterrupted stations and observing systems. 7.Focus on data-poor regions, poorly observed parameters, regions sensitive to change, and key measurements with inadequate temporal resolution as high priorities for additional observations. 8.Specify to network designers, operators and instrument engineers at the outset of system design and implementation the long-term requirements, including appropriate sampling frequencies. 9.Promote the conversion of research observing systems to long-term operations in a carefully- planned manner. 10.Data management systems that facilitate access, use and interpretation of data and products should be included as essential elements of climate monitoring systems.

15 WMO 15 1.A quality descriptor will accompany every real-time observation distributed to the ocean community. 2.Subject all observations to some level of automated real-time quality test. 3.Sufficiently describe the quality flags and quality test descriptions in the accompanying metadata. 4.Observers should independently verify or calibrate a sensor before deployment. 5.Observers should describe their method / calibration in the real-time metadata. 6.Observers should quantify the level of calibration accuracy and the associated expected error bounds. 7.Manual checks on the automated procedures, the real-time data collected and the status of the observing system must be provided by the observer on a time-scale appropriate to ensure the integrity of the observing system. Seven Data Management Laws

16 WMO 16 Recommendation Region V should begin to implement proper data quality techniques into their newly developed marine observation platforms - now – before the instruments are placed in the water.

40 WMO 40 International Tsunameter Data Assembly Center The worldwide tsunami observation network also requires a real-time, data assembly center to provide continual monitoring and quality control of Deep-ocean Assessment and Reporting of Tsunamis (DART®) water pressure/height observations. The Data Assembly Center monitors the various real-time transmission of DART ® messages depending on the operating mode of the bottom pressure recorder. Transmission of real-time water level heights occurs when the tsunami detection algorithm is triggered by a seismic event, when interrogated by the NOAA Tsunami Warning Centers (TWCs) or NDBC, or at pre-scheduled intervals.

41 WMO 41 Tropical Atmosphere Ocean Data Assembly Center Processing of Automated Distribution Service messages from Service Argos. It uses both the TAO calibration database and calibration files to convert raw data to engineering units and also calculates buoy positions. An automated real-time QC is performed for gross error checking and then the TAO database is updated with the corrected data. The TAO Real-time Data Monitoring Subsystem supports daily, weekly, and monthly QA/QC activities by providing on-demand data checking functionality to the DAC. In addition to the automated gross error checking, the real-time data monitoring subsystem provides on-demand reports for once- daily, thorough examination of all current buoy data and detailed review of the real-time data.

42 WMO 42 U.S. Voluntary Observing Ship (VOS) The United States Voluntary Observing Ship Project Mission The mission of the Voluntary Observing Ship (VOS) project is two-fold: (1) to collect and disseminate critical real-time maritime weather observations through the recruitment and support of ships to fulfill National needs and International agreements supporting commerce, forecasts and warning programs, and the Safety Of Life At Sea (SOLAS) worldwide, and (2) to define the global climate and help measure extreme weather events, climate variability, and long-term climate changes. VOS operates at no cost to the vessel, with communication charges, observing equipment and reporting supplies furnished by the National Weather Service. Port Meteorological Officers Port Meteorological Officers (PMOs) support observing programs aboard Voluntary Observing Ships. They are responsible for recruitment of new vessels as observers, and also for ensuring the quality of observations from vessels actively participating in the program.
