Important questions in the view of thermally induced flows are: 1. large scale meteorological conditions for the formation of the flow systems and their frequency of occurrence, 2. physical properties of flow systems in different development stages and 3. their impacts on thermal stress and air quality.
Hence, sub-project 8 (TP 8) will investigate the Urban Atmospheric Boundary Layer with special focus on the influence of thermally induced flow systems by determining the vertical distribution of meteorological parameters (wind speed, wind direction, temperature and humidity) as well as air pollutants (nitrogen dioxide, ozone, aerosol particles), black carbon and carbon dioxide in four intense observation periods (IOP) up to 1000 m height. These vertical soundings will be complemented by a mobile monitoring station, measuring the same compounds on ground during the IOPs.
For areas with a lack of measurement data, diffusive samplers will be set up to perform long-term observations (LTO) of nitrogen dioxide, nitrous gases and ozone. LTOs of urban climate in Stuttgart will be continued and improved. Data will be shared with other partners for joint research in Module B.
TP 8 will contribute to the development and testing of concepts, analysis tools and components of the data-warehouse. TP 8 will also participate in model validation studies and contribute to application tests.
