PRISM - putting all the pieces of the Earth togetherAmsterdam 13 December 2001 In December 2001, 21 European partners started with the PRISM project. Goal of this project is to integrate all already available Earth research models, like climate models, atmospheric models, sea-ice models, etc, into one large coupled model. PRISM could the be used to study all effects that certain measures, or events could have on the Earth system as a whole.
PRISM is a project in the Climate and Environment Programme of the European
Union. The overall formal objective of PRISM
is to develop a pilot infrastructure that establishes a distributed network
for Earth System modelling. For the Earth System PRISM will develop a flexible model structure, consisting of interchangeable components that exchange
information through standard interfaces with a universal coupler or directly
with each other.
Developing code couplers is not an easy undertaking, as experiences is for instance engineering simulation have shown.
The components of PRISM are models of the Earth's subsystems, including the atmospheric
and ocean circulation, atmospheric chemistry and marine bio-geochemistry,
land surface processes, and sea ice. These were developed by the individual partners.
The interchangeability of system components will enable flexible set-up
and extension of Earth model configurations. PRSIM will allow for the evaluation
of ensembles of simulations with different model configurations in order
to reduce uncertainties in predictions of future climate.
By integrating subsystem models into an Earth System model PRISM will likely could
become an important tool for the International Geosphere-Biosphere Programme
(IGBP). IBGP aims to describe and understand the interactive physical, chemical
and biological processes that regulate the total Earth system, the unique
environment that it provides for life, the changes that are occurring in
this system and how they are influenced by human activities.
