WGISS TASK TEAM PRESENTATION

• Task Team Name: WGISS Test Facility for CEOP (WTF-CEOP)
• Task Team Lead Name and Contact Information:
  Satoko Miura
  JAXA/EORC

• Purpose/Rationale:
  The purpose of the WTF-CEOP is to provide assistance to the CEOP science community in the development of data services associated with CEOP data integration.
• Origin of the Task Team
  The Coordinated Energy and Water Cycle Observation Project (CEOP) was initially motivated by the World Climate Research Programme (WCRP) Global Energy and Water Cycle Experiment (GEWEX) international efforts focusing on the measurement, understanding and modeling of water and energy cycles within the climate system. The requirements of GEWEX, the Climate Variability and Predictability (CLIVAR) initiative, the Climate and Cryosphere (CliC) Project and the other WCRP core projects as well as the climate research community at large have been taken fully into account in planning the assembly of a coordinated data set that will serve numerical modeling and analyses needs. Plans are for CEOP to assist research into the global atmospheric circulation and changes in water resources. CEOP has gained the interest of other international organizations outside of the WCRP community, as evidenced by the proposal for an Integrated Global Water Cycle Observations (IGWCO) theme within the framework of the International Global Observing Strategy Partnership (IGOS-P), which has re-affirmed CEOP as ‘the first element of the IGWCO’. IGOS is a component of the Committee on Earth Observation Satellites (CEOS).
  
  Dr. Toshio Koike, lead scientist of CEOP, approached CEOS with a request for JAXA, NASA, ESA and EUMETSAT to contribute data to the CEOP project. In addition, Dr. Koike approached CEOS WGISS with a request for assistance providing technology to develop a distributed CEOP data distribution and analysis prototype system.
• Goals and how they relate to WGISS
  Develop a WTF-CEOP system, based on existing CEOS WGISS member tools and technology, for distribution of CEOP data, including:
• Support gathering satellite data from providers (JAXA, NASA, ESA, EUMETSAT)
• Support data discovery (search for CEOP data)
• Support data selection (through menu selection)
• Provide basic functions: plotting, viewing data, comparing data, downloading data
• Provide data integration functions: methods of integration of in-situ, model output and satellite data.
• Implementation Strategy - High level requirements:
  1) Provide for selection, viewing and download of four types of CEOP project in-situ data, including accessing of in-situ data from a remote in-situ data archive.
  2) Provide for selection, viewing and download of CEOP project in-Model Output Location Time Series (MOLTS) data, including accessing of in-situ data from a remote MOLTS data archive.
  3) Provide for selection, viewing and download of CEOP project satellite data, including accessing of satellite data from a remote in-situ data archive.
  4) Provide for selection, viewing and download of CEOP project model output data, including accessing of model output data from a remote in-situ data archive.
  5) Provide methods for integration between the 4 types of CEOP data.
  6) Provide methods, according to scientist’s requests, that will increase the efficiency of scientific research on the water and energy cycle.

  CEOP Phase II:
• Part 1 (analysis of CEOP Phase I datasets) 2005-2006
• Part 2 (resume gathering data, continue analysis) 2007-2010
• Potential External Partnerships:
  CEOS WGISS, with JAXA as the lead agency, is working directly with:
• Members of the CEOP project Science Steering Committee.
• Representative from each of the 3 data archive sites (NCAR, CSDIC and MPI).
• Dependencies & Relationships to Other TT Activities:
  IDN TT - creation of GCMD CEOP portal and ingest of CEOP DIFs.
  Collaboration with the CEOS WGCV (Working Group on Calibration and Validation) is being explored.
  Collaboration with the WTF for Core Test Sites is being explored.
• Relationship of TT Activities to WGISS Goals and Activities:
  WGISS aims to assist CEOS participating members and associates, as data and information providers supporting users worldwide towards easy access and application of Earth observation data and information.
  WTF-CEOP provides access to many types of satellite data provided by JAXA, NASA, ESA and EUMETSAT in an integrated manner with in-situ data from 35 locations globally and model output data from 10 different agencies.
  
  To maximize the impact and benefit of WGISS activities, the group will coordinate with other CEOS groups, non-CEOS agencies and organizations, including governmental and non-governmental organizations that have interests, resources and networks supporting EO data development and exchange.
  WTF-CEOP is exploring partnering with the WGCV, and the basic purpose of WTF-CEOP is to support the global water cycle research community.
  
  WGISS will provide a forum for worldwide cooperation and management of compatibility of agency policies, protocols and interfaces, in which technical and administrative issues can be addressed, and where critical interactions between technical implementers can take place.
  Through participation with CEOP, WTF-CEOP is indirectly interfacing with major science organizations such as WCRP and GEWEX.
  
  The archive management, data production, procedural consistency, web presentation, access interoperability and delivery of the data and derived metadata and information is the focus for WGISS.
  WTF-CEOP is accessing data from 3 archive centers globally, presenting the data via the web, developing methods for data integration (satellite data with in-situ and model output data) and supporting delivery of Earth Observation data.
  
  The major CEOS goal is to coordinate the development of space missions so as to provide a range of data and information services better attuned to the needs of users than could be delivered by provider members and associates acting independently. This must be followed through from the mission definition to the delivery of products and services at the point of use. At that point of use, ease of access, ease of use, ease of interuse, and reliability of information will demonstrate the success (or otherwise) of achieving the CEOS mission. To intensify pursuit of that objective, CEOS embarked in 1997 on an Integrated Global Observing Strategy (IGOS) that is aimed at matching more closely availability of data-derived services to the needs of users. WGISS's contributions to the IGOS initiative have been the development of the WGISS Test Facilities (WTFs) to support specific projects.
  The CEOP project is working closely with IGOS (e.g. holding joint plenary meetings and planning joint workshops) and WTF-CEOP is participating in these meetings and activities. In addition, WTF-CEOP is being demonstrated at a variety of science conferences and the science community is being asked to make requests for customized data processing functions (e.g. calculation of the diurnal cycle) that will facilitate use of the data by scientists.
• Expected Duration of Task Team: Ongoing
