Carbon isotope measurements as a tool to gain insight into atmospheric processes

https://cesnet.zoom.us/j/94167862089

Although aerosol particles are a small part of the atmosphere, they have a significant impact on, e.g., air quality, climate, or health. Isotope analysis of atmospheric aerosols is a possible way to study the processes that take place in this atmospheric component. Carbon is one of the relatively abundant elements in aerosols, so isotopic composition analysis of stable carbon ¹³C can be used, for example, to roughly analyze the sources of these particles. A parameter that may provide more insight into the behavior of particles in the atmosphere is the distribution of δ¹³C between the aerosol and gas phases. This inter-phase distribution of δ¹³C as a function of different seasonal sources of ¹³C was the focus of our research. In this lecture, the results of a seasonal study of δ¹³C measurements in the fine aerosol and gaseous phase at the Prague-Suchdol station will be presented.
