The focus of the Meteorology and Air Quality group is on the understanding of processes in the Atmospheric Boundary Layer, with particular emphasis on the interaction of the atmosphere with the (vegetated) land surface. The research focusses on the measuring and modelling of the relevant atmospheric and related land surface processes on the local and regional scale. The group provides a complete study in Meteorology and Air Quality as part of the educational programme named Soil-Water-Atmosphere. In addition contributions are made to Environmental Sciences, and Geo-Ecology. For example, students are guided in the basics of weather forecasting and climate processes, desertification and land use, cumulus and larger scale cloud processes,turbulence and dispersion, and many other atmospheric subjects. The group cooperates within the Wageningen research schools (WIMEK and PERC), as well as the Dutch 'Buys Ballot School' on fundamental processes in the climate system.
