Abstract
Europe's widely distributed climate modelling expertise, now organized in the European Network for Earth System modelling (ENES), is both a strength and a challenge. Recognizing this, the European Union's PRISM infrastructure project (PRogram for Integrated earth System Modelling) aims at designing a flexible and friendly user environment to assemble, run and post-process Earth System models.
The proposed PRISM system includes:
community wide input and requirement capture through user/developer meetings, workshops and thematic schools;
definition and promotion of scientific and technical standards to increase component modularity;
an end-to-end software environment (coupling and I/O system, user interface, diagnostics) to launch, monitor and analyse complex Earth System Models built around state-of-art community models; up to now, more than 30 models, representing one of the 6 identified components (atmosphere, atmosphere chemistry, land surface, ocean, sea ice and ocean biochemistry), have expressed interest in PRISM;
testing and quality standards to ensure HPC performance on a variety of platforms.
This science driven project (help the scientist spend more time on science), led by 22 institutes and started in December 2001 for a duration of 3 years, benefits from a unique gathering of scientific and technical expertise. On a longer term, PRISM embodies a pilot infrastructure project directed to the establishment of a distributed European computing facility for Earth System modelling.
