The 2016 Outstanding Student Poster and PICO (OSPP) Award is awarded to Jan-Marcus Nasse for the poster/PICO entitled:

I am a PhD student at the Institute of Environmental Physics of Heidelberg University. The topic of my PhD project in the Atmosphere and Remote Sensing group is the investigation of Polar halogen chemistry in the lower troposphere.
Using optical measurements of atmospheric trace gas concentrations from a new instrument currently operated at the German Antarctic station Neumayer III, I study the chemical processes that determine the release and fate of halogen compounds in the atmosphere, in particular the highly reactive radicals BrO, IO and ClO. This is key to understanding the influence of halogens in Polar atmospheric chemistry and effects like the frequent destruction of tropospheric ozone or the oxidation of gaseous elemental mercury which can have an impact on climate and the biosphere.
The poster presents the design and first results of the new instrument developed in the first year of my PhD project.
