Two GEWEX Panels, GASS and GLASS, oversee GEWEX modeling and prediction activities, which include development and improvement of boundary layer, cloud, and land-surface parameterization schemes to ensure their successful integration into global circulation models.
The co-chairs of GASS and GLASS are members of the Working Group on Numerical Experimentation (WGNE), which is jointly sponsored by the World Climate Research Programme and the World Meteorological Organization Commission for Atmospheric Sciences. WGNE leads the development of atmospheric models for both climate studies and numerical weather prediction.
