Data are available from seven ceilometers (located at Telfs, Kematen, Innsbruck Airport, Innsbruck City and Jenbach, Radfeld and Kufstein), providing coverage in and around the city of Innsbruck and along the valley towards the valley exit region. Meteorologists from GSA and University of Innsbruck will co-supervise a student, thus making a joint effort to understand the spatial and temporal patterns of mixed layer heights as found in the ceilometer reflectivity dataset. First, the automatic detection of boundary layer heights from ceilometers will be compared with other methods (e.g. radiosonde, microwave radiometer). Next, the variation in boundary layer height along the Inn Valley will be investigated through case studies in different seasons and for different weather patterns. Finally, differences in boundary layer height over Innsbruck compared to the surroundings
will be quantified. This project brings together expertise at GSA and UIBK on boundary layer development, mountain meteorology and urban atmospheres. Findings will support TEAMx efforts to improve understanding of the mountain boundary layer and will be of interest to both the mountain meteorology and urban climate communities.
