The two primary users of climate models are the research community, whose goals are to advance the understanding of the climate system, and the operational community, which uses models for the production of climate prediction products in response to societal demands. The two groups are connected because research is crucial for constructing and evaluating the models needed to produce useful products, and the operational infrastructure required to produce these products (such as a sustained observing system, modeling system, and resulting model assimilated data products that result)

Many of the measurements and observations used to define climate are made in the arena of weather prediction, and many of the atmospheric processes and feedbacks that influence short-term weather contribute to climate. Therefore, the panel recognizes that strong weather forecasting capabilities are necessary preconditions for effective climate model development, and close ties should be maintained between climate and weather modeling activities.

The Need for Open Access to the Most Appropriate Computer Architecture The most effective means to obtain superior computer performance is to utilize machines with powerful processors; small, fast networks; and rapid memory access. Currently, Japanese parallel vector supercomputers provide the fastest and most capable architecture for the sustained processing of climate model codes.

The Need for a Common Modeling Infrastructure Effective climate model development is often hindered by an incompatibility between model components developed in different groups. A protocol to facilitate the scientific exchange of common diagnostic tools, the interchange of model components, and the exchange of data in a common data format is not yet in general use.

Institutional Arrangements for Delivery of Climate Services The panel has argued that the suite of designated "Climate Services" consisting of the establishment and sustenance of a climate observing system, the production of useful model products on the global and regional scale, and delivery and dissemination of these useful products would satisfy societal demands and would be of great benefit to the research community. In what form these climate services would be delivered; how much of the climate information would be developed and

an analysis of institutional and governmental constraints for sustaining a climate observing system, modeling the climate system, communicating with the research community, and delivering useful climate information; 4. an analysis of the human resources available and needed to accomplish the above tasks; 5.
