3rd WGNE Workshop on Systematic Errors in Climate and NWP Models

San Francisco, February 12-16, 2007

The JSC/CAS Working Group on Numerical Experimentation (WGNE) and the Program for Climate Model Diagnosis and Intercomparison (PCMDI) will host a Workshop on Systematic Errors in Climate and NWP Models. The workshop will be held in San Francisco, CA, USA, during the week of February 12th, 2007. The workshop will be held at the newly renovated financial district Hilton.

Although the principal goal of the workshop will be to increase understanding of the errors and their causes in coupled climate models, it is anticipated that, as in previous workshops, the focus will be on Atmospheric General Circulation Models (AGCMs). A wide variety of diagnostic techniques will be discussed, including traditional analysis methods applied to global models, process studies, the use of diagnostic models (e.g., single-column, cloud-resolving), and simplified experiments (e.g, AMIP, aqua-planet). Of special interest will be studies that consider errors found in multiple models (i.e., are pervasive) and that are likely to have implications for climate projections. Errors relevant to both component and coupled models (e.g., surface fluxes) will also be of particular interest.

It is hoped that by inviting contributions based on a variety of diagnostic approaches, awareness and understanding of the causes of systematic errors will be increased, and that this might lead to a more coherent strategy for future advances in this area.

The following WCRP working groups will contribute to the coordination of the workshop: The Working Group on Coupled Models (WGCM), the GEWEX Model and Prediction Panel (GMPP), and the Working Group on Seasonal to Interannual Prediction (WGSIP).
