2. CEOP INTRODUCTION/SCIENCE OVERVIEW BY CEOP LEAD SCIENTIST (T. KOIKE)
The CEOP Science Strategy and how it will be addressed at the meeting will be introduced.
Satellite and in situ data Integration and assimilation topics will be introduced with model
related issues. CEOP is seeking to achieve a database of common measurements from both in-situ
and satellite remote sensing measurements, as well as matching model output that includes Model
Output Location Time Series (MOLTS) data along with four-dimensional data analyses (4DDA;
including global and regional reanalyses) for a specified period. In this context, carefully
selected reference stations are linked closely with the existing network of observing sites
involved in the GEWEX Continental Scale Experiments (CSEs), which are distributed around the world.

3. CEOP IMPLEMENTATION STRATEGY SUMMARY (S. Benedict)
In-situ measurements, enhanced satellite observations, and model products are the fundamental
components of the CEOP strategy, and a uniquely co-ordinated set of these data types is
necessary to address the CEOP scientific objectives. Planned, co-ordinated and structured
international commitments, co-operation and collaboration are therefore crucial elements ofthe
implementation of CEOP. Acknowledgement of a wide range of individual and collective efforts
that are shaping CEOP towards a realization of these goals is important in assessing the level
of success so far. It is also necessary to acknowledge that current commitments are ad hoc and
barely sufficient to have shaped the CEOP EOP-1 dataset, for July-September 2001. A redoubling
of efforts to formalize current agreements is necessary to reconcile this situation and achieve
longer-term goals.

4. CEOP DATA MANAGEMENT WORKING GROUP STRATEGY OVERVIEW/UPDATE (S. Williams/H-J Isemer)
A great deal of information has recently been made available concerning the characteristics of
the CEOP reference sites. This information has been placed in the CEOP Reference Site Table at:
http://www.joss.ucar.edu/ghp/ceopdm/rsite.html. Sufficient information has also now been obtained
to describe the characteristics of an initial CEOP dataset (EOP-1) for the period July through
September 2001. This exercise has provided CEOP with a template for implementation of its annual
cycle datasets that will follow-on from EOP-1 and which form the key deliverables of CEOP. Two of
these, EOP-3 and EOP-4 cover the period from 1 October 2002 up to the end of 2004. The effort
undertaken by the CEOP Reference Site Data Center at the University Corporation for Atmospheric
Research (UCAR), Joint Office for Science Support (JOSS), to develop a composite EOP-1 dataset
from the wide range of measurements and formats received from the CEOP Reference Sites has enabled
the CEOP Data Management Working Group to meet an important milestone. This activity has shown,
however, that adherence by the Reference Sites, to a consistent format, such as that characterized
by EOP-1, for submittal of data associated with the EOP 3 and 4 datasets, is especially important
to ensure an efficient continuation of the CEOP dataset development and delivery process.
A process for the timely delivery of the CEOP annual cycle datasets in the likeness and quality
established for EOP-1 must be established.

5. CSE/CEOP REFERENCE SITE CONTRIBUTIONS SUMMARY
The configuration of the EOP-1 in situ dataset has marked an important milestone in CEOP that
could not have been accomplished without the support of the Reference Site Spokespersons and
Managers. The CEOP reference sites located in the six most comprehensive GEWEX CSEs namely,
GAPP (Mississippi River Basin), BALTEX (Baltic Sea region), MAGS (Canadian Mackenzie River Basin),
LBA (Amazon region), CAMP (Asian monsoon region) and AMMA/CATCH (Western African Monsoon Region),
are being provided, through Multi-National commitments, to improve the collective contribution of
the CSEs to the global requirements of CEOP.An earlier workshop has focused on the Reference Site
contributions to defining the final format for future CEOP datasets including the assembly and
timely delivery of the CEOP annual cycle datasets. The Reference Site representatives will be
asked to review the outcome of the earlier meeting from their own perspectives and to discuss
individually their plans to deliver data, which meet the established criteria for the future
datasets, in an efficient manner. Representatives will briefly discuss their contributions and
note their main issues:
- BALTEX (Grassl/Isemer)
- MAGS (Goodison)
- GAPP (Lawford / Brown)
- LBA (Marengo/von Randow)
- GAME/CAMP (Koike)
- AMMA/CATCH (Lebel/Depraetere)

6. CEOP WATER AND ENERGY SIMULATION AND PREDICTION STATUS (J. Roads, J. Marengo, K. Mitchell, E. Berbery)
A CEOP Water and Energy Simulation and Prediction (WESP) Working Group has been organized.
WESP studies are designed to understand what components of the global water and energy cycles
can be measured, simulated, and predicted at regional and global scales. In particular:
(1)what are the gaps in our measurements? (2) What are the deficiencies in our models?
(3) What is our skill in predicting hydroclimatological water and energy budgets? Starting
from the current efforts to close simplified vertically integrated water and energy budgets
with observations and analyses, and beginning efforts to simulate these budgets regionally,
CEOP will begin the effort to transfer this knowledge to global scales, include more water
and energy cycle processes, and begin to examine the vertical structure in the atmosphere and
land. Specific tasks for the WESP working group during CEOP include: Summarizing component and
coupled system modelling studies currently underway; Articulating scientific issues that need
to be addressed in light of advances in each CSE; Defining guidelines for commonality and
standards in the background fields and measure of progress; Devising the detailed nature of
the experimental periods. Results from this work will be shown and specific issues related
to these objectives will be addressed.

7. CEOP SATELLITE DATA INTEGRATION STRATEGY (Koike, Fischer, Burford, Bosilovich, Goodison)
A CEOP Satellite Data Integration Working Group has made progress on the satellite data
integration activity under development by NASDA and the University of Tokyo (UT). It has
been reconfirmed that a 500 tera-byte data archival system at UT will be available for the
CEOP satellite data integration work, which focuses on data collection, visualization and
analyses. NASA may also contribute a CEOP Satellite Data Integration Center in the USA
focused on land surface analyses (LDAS/GLDAS) that will complement the work at the Japanese
Center. Both elements of this concept are contained in a proposal for a CEOP CEOS/WGISS Test
Facility (CEOP-WTF) promoted by NASDA. The CEOP Satellite Data Integration coordination
activities have led to decisions that were made relative to the physical aspects of the CEOP
satellite dataset(s) and actual sample CEOP Satellite EOP-1 datasets, encoded in "tar"/"gzip"
form, have become available through anonymous FTP server. Related satellite data integration
issues will also be addressed.

8. CEOP MONSOON SYSTEMS STRATEGY OVERVIEW (W. Lau, R. Mechoso)
A CEOP Monsoon Systems Working Group has been addressing the accomplishment of one of the
main CEOP aims associated with the documenting of the seasonal march of the monsoon systems,
assessing the monsoon systems driving mechanisms, and investigating the possible physical
connections between such systems. It was recommended at the Groups first implementation
planning workshop (September 2002), that the Working Group proceed with a CEOP Inter-monsoon
Model Study (CIMS). CIMS will be an international research project to validate and assess
the capabilities of climate models in simulating physical processes in monsoon regions around
the world. For CIMS, a major effort will be devoted to defining the data requirements, and
modeling strategy for validating model physics. Validation data will be derived from CEOP
reference sites, which include GEWEX CSE and planned CLIVAR field campaign sites. Numerical
experiments will be designed to target the simulation of fundamental physical processes that
are likely to uncover limitations in model physics. The specific issues related to these
objectives will be addressed.

9. MODEL STRATEGY OVERVIEW (K. Mitchell, S. Milton, M. Bosilovich, J. Roads, J. Marengo, T. Matsumara)
Following the discussion at the September 2002 CEOP Status meeting on CEOP Model Output
product development, an action was undertaken by Drs Ken Mitchell and John Roads, with
others, to standardize the CEOP Model Output requirements. As a result of this action
a document has been produced which incorporates a framework that provides guidance for
CEOP model output generation at NWP centers, Meteorological agencies and data assimilation
centers. The CEOP Model Output Guidance Document and all the latest inputs related to the
requirements for this part of the project reside on the CEOP Data Management Web Page:
http://www.joss.ucar.edu/ghp/ceopdm/. Since the meeting, commitments, which are aligned
with the guidance strawnam document, have been obtained for the provision of CEOP model
products from major National and Multi-National Centers including the JMA, NCEP, DAO, ECMWF,
the UK Met Office, CPTEC and BMRC. It has also been announced that the Max Planck Institute
for Meteorology (MPIM) at Hamburg, Germany would contribute support to CEOP by assisting with
the centralized handling and retention of the CEOP model output data being generated by the
various contributing centers. Work is underway to integrate the CEOP data into a World Data
Center (WDC) on Climate database scheme at MPIM. The most efficient input, storage and access
structure needs to be addressed with other issues related to CEOP Model Output requirements
including the possibility that mirror sites for some or all of the CEOP model output data
products may be established in Asia and the USA.
