Scope

More demanding air quality policies as well the established role of atmospheric compounds in climate change have prompted the issue to assess the reliability of our level of understanding of the physical and chemical processes influencing the distribution of atmospheric compounds. In particular, the surface and atmospheric boundary layer play a key role in the distribution and evolution of atmospheric compounds since the majority of sources and sinks are located at or near the Earth's surface.

The development of new measurement and data analysis techniques as well as the possibility of using finer scale models allow us to tackle new questions related to the role of small scale processes on atmospheric compound cycles. This workshop aims at reviewing our current knowledge of such physical and chemical processes and their impact on the larger spatial and temporal scale distribution of atmospheric compounds. Particular emphasis will be put on promoting the interaction between the atmospheric physics- and chemistry communities. An important aspect to assess is whether the new observation and modelling techniques are suited to address the key questions in surface and boundary layer processes. Consequently, a second objective is to discuss the need of future experimental campaigns addressing the influence of surface and boundary processes on atmospheric chemistry. Therefore, we also aim at a close interaction of modellers and experimentalists.

We explicitly ask the invited speakers to focus on identifying their main needs in terms of modelling activities and experimental field research and in posing open questions relevant to the workshop subjects using a maximum of 1 hour for the presentation leaving ample time (30min) for discussions.
