  1. CEOS Precipitation Constellation – WGISS Liaison Karen Moe, WGISS Applications Subgroup Chair WGISS-28 Pretoria, South Africa September 30, 2009

  2. WGISS Current Focus • Provide satellite arm of GEO System of Systems • Innovative contributions that will persist, and can be reused • Work closely with and support CEOS Virtual Constellations • Work closely with and collaborate as appropriate with WGCV • Support the CEOS Data Democracy initiative. (Jim Gleason, USA ; Pepijn Veefkind, KNMI)

  3. WGISS and Precipitation • Erich Stocker/NASA and Masayuki Ohta/JAXA presented PC overview to WGISS-26 Sep. 2008 • PC contributions of data to WGISS Projects in GRID and Sensor Webs Interest Groups • What should be the relationship of GDaWG with other groups such as the CEOS WGISS? • Initiated liaison approach for WGISS collaboration with PC’s GPM Data Working Group (GDaWG) • Invited WGISS to GDaWG in June 2009 • WGISS-26 Action • Satoko, Karen to identify liaison candidates for Precipitation Constellation and WGISS.

  4. WGISS Contribution to PC • Precipitation data differs significantly from 2D surface data, such as land images. Participation in GDaWG can help: • Clarify the unique needs of layered precipitation data • Highlight implications for geospatial metadata and services • Provide PC perspective and feedback on metadata and system prototype implementations • WGISS liaison to GDaWG recommended to • Determine PC data production issues & address from user’s point of view • Provide experience with data tools & services (e.g. subsetters, browse, notification services, help desk, protocols, metadata)

  5. GPM Data Working Group (GDaWG) • GPM Data Working Group (GDaWG) meeting was held Paris, 19 June 2009. • The role of the GDaWG with respect to the CEOS PC was discussed, as well as the WG charter. • Erich Stocker presented a WGISS overview presentation and received concurrence to pursue a liaison role. • GDaWG has JAXA, NASA and ESA/CNES active participation and is looking for increased involvement by China (FY3) and Russia, among others. • GDaWG would like to adopt a data democracy position (see next slide for details).

  6. Data Democracy in GDaWG • The key to the data democracy is • Automated access to data for users without manual intervention or permission needed in the middle of access • e.g. interactive acknowledgement of data policies, interactive yes or no windows, etc. • Anything that interrupts a decision support tool’s access to the data it needs in an automated fashion is not data democracy.

  7. PC / GDaWG Opportunities • CEOS PC meeting activity is light, however there may be a 1-day PC membership meeting the last week of Oct 2009 during the Precipitation Measuring Missions (PMM) science meeting in Salt Lake City, Utah, USA • Next GDaWG is tentatively planned for May/June 2010 timeframe in conjunction with an upcoming GPM international meeting, or possibly a separate meeting in Argentina or Tokyo

  8. PC – WGISS Discussion • WGISS Liaison? • May/June 2010 GDaWG?
