Following the recommendations of the European climate research community (Euroclivar, November 1998), it is proposed to undertake a "Programme for Integrated earth System Modelling" as a pilot infrastructure project for the establishment of a climate research network. The work plan foresees
the creation of a European management structure for developing, coordinating and executing a long-term programme of European-wide, multi-institutional climate simulations;
the development of a set of portable climate community models and associated diagnostic software under standardised coding conventions that can be accessed by all European scientists;
the execution of a first suite of joint simulations.
PRISM will greatly enhance the efficiency of earth system modelling in Europe and it will pave the way for the establishment of a European Climate Computing Facility. The expected product will be a flexible, efficient, portable, and user friendly community infrastructure for earth system modelling and climate prediction.
