A Plan for CEOS WTF for CEOP andCEOP Satellite Data Integration Implementation
1 Background
The Coordinated Enhanced Observing Period (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 andCryosphere (CliC) Project and the other WCRP core projects as well as the climate research community atlarge have been taken fully into account in planning the assembly of a co-ordinated data set that will serve
numerical modeling and analyses needs. Plans are for CEOP to assist research into the global atmosphericcirculation 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 acomponent of the Committee on Earth Observation Satellites (CEOS).
Professor T. Koike, the Lead Scientist for CEOP, on behalf of Dr David Carson, Director of WCRP and Dr
Soroosh Sorooshian, Chairman of the GEWEX Scientific Steering Committee (SSG), arranged for the initiallaunching meeting of the formal CEOP implementation process to be held at the Earth Observation ResearchCenter (EORC) of the National Space Development Agency (NASDA), in Tokyo, Japan, from 6-8 March
2002. Dr T. Ogawa, Director of EORC, hosted the meeting. More specifics about CEOP and the Kick-off
meeting can be found through the CEOP Internet site: http://monsoon.t.u-tokyo.ac.jp/ceop/.
The lead organization representing the CEOS agencies in the Working Group on Information Systems andServices (WGISS) Test Facility (WTF) for CEOP is proposed to be MEXT/NASDA, with possible support
from other CEOS members and CEOS affiliates.
The WTF for CEOP will include data and information systems supported by CEOS agencies and affiliates andtwo CEOP Satellite Data Integration Centers (CSDICs), one at the University of Tokyo (UT) under thecooperation with NASDA and the other at NASA’s Goddard Space Flight Center (GSFC). The WTF forCEOP will handle Earth observation satellite data, in-situ data, numerical model output, and four-dimensional
data assimilation for atmospheric profiles over land and ocean, land and ocean surface and land sub-surface.
For the WTF for CEOP, OpenGIS technology and visualization tools will be utilized.
The CEOS agencies data systems as WTF for CEOP will provide catalogue services for level 1 –3 products
and also provide subsetted (edited) level 1b & level 2 for CEOP validation sites (“CEOP customized product”)
and standard level 3 Earth observation satellite data.
The CSDIC at UT will receive CEOP customized level 1b & level 2 and standard level 3 Earth observation
satellite data from CEOS agencies’ data systems and information systems and archive them. CSDIC at UT will
distribute integrated CEOP products to users. Under the WTF for CEOP collaboration, the CSDIC at UT willdevelop catalogue interoperability with CEOS agencies’ systems by using CEOS developed protocols. Inaddition, the CSDIC at UT will exchange data and information with CEOS agencies and affiliates as well asusers through networks. Integrated CEOP products overlaid with other EO satellite, in-situ and model output
will be delivered to users by Web Mapping Technology and other visual technologies through networks.
NASA has developed a Global Land Data Assimilation System (GLDAS) that uses various new satellite andground based observation systems within a land data assimilation framework to produce optimal output fieldsof land surface states and fluxes. GLDAS includes four components implemented globally at ¼ degree
resolution (higher resolutions are planned) in near real time: land modeling, land surface observation, landsurface data assimilation and calibration and validation. The core advantage of GLDAS is its use ofsatellite-derived observations (including precipitation, solar radiation, snow cover, surface temperature, andsoil moisture) to realistically constrain the system dynamics. This allows it to avoid the biases that exist innear-surface atmosphere fields produced by atmospheric forecast models, minimize the impact of simplified
land parameterizations, and to identify and mitigate errors satellite observations used in data assimilation
procedures. These value-added GLDAS data will improve land surface, weather, and climate predictions byproviding global fields of land surface energy and moisture stores for initialization. GLDAS is a natural andimportant tool for CEOP because in a globally consistent manner, it will integrate the information frommultiple models and observation platforms to provide the best available assessment of the current state of theland surface. CEOP has requested that NASA further develop GLDAS as another CSDIC.

4 Purpose of this document
This document proposes a Work Plan for the CEOP WGISS Test Facility. It is primarily based theProposed WTF/CEOP material (3.2 [R1]) presented to CEOS/WGISS in Tokyo at February 2002. It isorganized as follow:
Section 5 describes the high level technical objectives of the WTF/CEOP. There are three items for
prototyping and its evaluation. Also, three phased activities concept for satellite data integration isdescribed.
Section 6 identifies the workpackages for each phase, provides the planned schedule of activities
and identifies the main deliverables and milestones.
Section 7 gives the management plan for the WTF/CEOP project.

5 WTF/CEOP objectives
5.1

Three Prototyping and Evaluation activities for the WTF/CEOP satellite dataIntegration

The satellite data integration project has been designed to evolve in steps over the period from October
2002 up to the end of September 2004. In the initial prototyping and evaluation period, data will be required
to be sent from the satellite data archives of CEOS/WGISS member organizations to CSDIC at UT. The
CSDIC will integrate satellite 4D product with in-situ and model data validation. The 4D visualization
prototype will then be undertaken and finally an evaluation of the application and value of the 4D products
will be initiated along with the data access capability.

Two Phased Activities for Global Land Data Assimilation
The GLDAS proposes the following timeline:•Data Integration Period (2002-2005)– Compile the forcing data (obs and analyses) and assimilation data•
Including radiance observations (level 1), high-level satellite data products, in-situ
observations, and NWP land analyses.
– Long term archive (Goddard DAAC, NCAR, Japan)– MLDAS (Molts LDAS)•Reconfigure GLDAS to run only MOLTS points•
Access the global forcing for flexibility in point definition•
Smaller computing requirements, easier turnaround time. Good for R&D, landmodel intercomparison•
Link to CSE reference sites•Reanalysis Period (2006-2007 work activity)– 1/8 degree resolution; global land, CEOP time domain– Land model products (NOAH, CLM, VIC, others)–

Data assimilated value-added analysis

Itwill provide in particular access to all WTF/CEOP reference documents, minutes of meetings andteleconferences, status reports, threaded discussion group (?) future events and provide list of contactpoints and links to the various participating sites as well as to the WTF/CEOP demo site itself.

oMonthly progress reports. WTF/CEOP members will provide monthly reports on the status of theiractivities. These reports will be compiled and be distributed to all members by an email distribution list.
They will also be available on the WTF/CEOP web site.

Other communication means fax, one to one phone calls and outstanding teleconferences will also support

day-to-day work and will be organized as needed.
