Vortrag


The atmospheric layer that is adjacent to the Earth’s surface and varies in depth from a few hundred meters to a few kilometers is called the atmospheric boundary layer. Mountainous terrain exerts an important influence on the boundary layer and affects atmospheric transport and mixing processes at a wide range of temporal and spatial scales. An understanding of these topographic effects is needed for the correct representation of atmospheric boundary layers in numerical models that predict weather, air pollution concentrations, and climate change. In this presentation, I will demonstrate the complexity of the boundary layer in mountainous terrain using observations from recent field campaigns. The role of new and emerging technology including the use of airborne Doppler lidar and of unmanned aerial vehicles will be emphasized. I will highlight some ongoing research activities that have the objective to quantify boundary layer structure over mountain tops and to reduce transport uncertainty in models that estimate regional-scale carbon fluxes.
