Guidelines

The dissertation thesis will be based on:
- measurement and analysis of the equivalent black carbon data at a rural background station from multiple measurement levels above ground
- evaluation of the vertical gradient in respect to boundary layer and atmospheric stability
- comparison of the in-situ measurement with remote sensing data to estimate processes and changes in vertical distribution

Preliminary scope of work in English

The composition of atmospheric aerosols generally differs with the height above the Earth's surface. This applies also on the black carbon, one of the main light-absorbing aerosol component, ranking second among climate forcing agents after carbon dioxide. The 250 m high atmospheric tower at the Kosetice National Atmospheric Observatory presents a unique opportunity to study vertical gradient of atmospheric components over extended periods. With additional remote sensing instrumentation, the vertical distribution of black carbon could be compared also to vertical distribution of other parameters, and to columnar content of pollutants and other properties.
