Snow and ice are chemically active. The resulting fluxes of trace gases impact air quality and climate change as well as health, when the trace species are released to the aquatic environment and enter the food web. To better understand the underlying processes on a fundamental level, we do laboratory based experiments:

At the interface

The image illustrates the emerging picture of solvation of acidic trace gases at the air — ice interface as developed based on our recent X-ray photoemission and X-ray absorption experiments at the Swiss Light Source (SLS). We interpret the results from these two complementary methods as physisorbed molecular acid at the outermost ice surface and dissociation occurring upon solvation deeper in the interfacial region. ).
Investigate the fate of solutes at the surface of ice on a molecular level taking full advantage of core-level spectroscopy at the Swiss Light Source of PSI (SLS).

Multiphase systems

The phase of aerosol particles in snow changes with decreasing temperatures from liquid (green circles) to solid (yellow hexagons). As consequence, reactive processes in the bulk would become less feasible, while surface reactions occur remain in operation. (3-dimensional µCT reconstruction of snow: Schneebeli, WSL-SLF Davos).
Investigate the physical interactions and chemical reactivity of trace impurities in snow and ice in larger scale experimental systems that perfectly mimic environmental settings.
