AB: The Coordinated Enhanced Observing Period (CEOP) is a major initiative of the World Climate Research Program (WCRP) in cooperation with the World Meteorological Organization (WMO) and the Committee on Earth Observation Satellites (CEOS) under the framework of Integrated Global Observing Strategy Partnership (IGOS-P). It seeks to establish an integrated global observing system for measurement, understanding, modeling and predicting water and energy cycles within the climate system which responds to both scientific and social needs. The overall objectives of CEOP are 1) to use enhanced observation to better document and simulate water and energy fluxes and reservoirs on diurnal to annual temporal scales and to better predict these on temporal scales up to seasonal for water resource applications, and 2) to document the seasonal march of the monsoon systems, assess their driving mechanisms, and investigate their possible physical connections. NASA and JAXA are two of the major contributing agencies of CEOP. CEOP research requires the integrated analysis and inter-comparison of multiple-source data. There are three major sources of CEOP data: in situ measurements collected at field sites around the world, satellite remote sensing data and modeling outputs. The integrated analysis requires the co-registration of CEOP datasets. Generating a co-registered CEOP data set requires integrating numerical modeling results with in-situ and satellite observations. Inter-comparison of the numerical model results with the satellite observations is facilitated when the two products are represented in a common spatial reference system, typically an equirectangular latitude/longitude grid. Multiple tools and services are needed to perform data integration. Currently, the CEOP/GEWEX science community lack advanced tools to access the satellite data with the data services needed to support data integration. The CEOP Program initiated a discussion with the CEOS Working Group on Information Systems and Services (WGISS) to see if they could assist in solving this problem. CEOS WGISS initiated a project where the CEOS information technologists work closely with the CEOP scientists to collaboratively prototype a set of tools and services needed to support data integration to support CEOP science. The initial CEOS/CEOP Prototype, demonstrating a limited set of services needed for data integration, was completed and demoed spring 2005 at the CEOP meeting to wide acclaim from the CEOP science community. A second phase is currently being planned. Existing tools and software (e.g. OPeNDAP suite of clients and servers such as the Grads client and server, the Open Geospatial Web Coverage Server, and NASA's ECHO catalog system) are expected to be tailored to provide a wider set of the data services needed for data integration. From a broader perspective, the goals of the work are clearly aligned with the strategic objectives of the international CEOS community to develop new technologies to improve the study of the Earth system utilizing Earth observations from space and are consistent with goals of the Global Earth Observation Systems of Systems (GEOSS). The CEOP/GEWEX science communities have identified barriers they have met in their attempts to access and use satellite data resources, and this input has guided the development of the prototype effort. However, the results of this project will also serve other Earth system studies that rely on the integration of satellite and in situ data and model results.
