GABLS is a new project to improve the representation of the Atmospheric Boundary Layer (ABL) in models on the basis of an advanced understanding of the relevant processes. The ABL is an important aspect of the physics in regional and global models. It is particularly important when discussing coupled atmosphere/land-surface/ocean models. GABLS an international activity under the GEWEX Modelling and Prediction Panel (GMPP) aimed at stimulating and coordinating research on boundary layer physics. GABLS like GLASS and GCSS will undertake its work in association with the other components of WCRP, especially with the Working Group on Numerical Experimentation (WGNE). This interaction will ensure that GABLS establishes the same proactive posture in engaging the NWP/GCM community that has been used in GCSS and GLASS. GABLS will include representatives of the weather and climate modelling communities in their deliberations and have them present issues of relevance to large-scale models, which GABLS will then integrate into its work plans.
