Workshop on Evaluating the ocean component of IPCC-class climate models
Princeton, USA
Wednesday, 16 June, 2004 - Friday, 18 June, 2004
The CLIVAR Working Group on Ocean Model Development (WGOMD) organised a workshop at the NOAA Geophysical Fluid Dynamics Lab (GFDL) in Princeton USA on June 16-18 2004. About 100 experts in ocean modelling attended the workshop, which was hosted by Stephen Griffies of GFDL.
Motivation
The main goal of the workshop was to facilitate a dialogue between modellers, theorists, and observationalists on the physical integrity of a new class of high-end global ocean models, with the particular aim to articulate how best to move forward over the next decade to improve simulation realism. These new models have been developed over the past few years largely in response to the requirements of the 4th IPCC Assessment Report (AR4) due for publication in 2006. For many climate laboratories, the recent model development efforts were unprecedented in their intensity and scope.
