A science outpost in midnight sun

Photo of the air chemistry observatory of the German Neumayer III Antarctic station during Polar day. Located in a clean air sector south of the station, its main purpose is to record continuous, year-round data records of relevant particulate and gaseous trace components of the troposphere. As one of only few stations located in the very clean troposphere of Antarctica, its data sets are very valuable contributions to the GAW (Global Atmospheric Watch) station network and important to interpret trace compound records in Antartic firn and ice.
It furthermore serves as a platform to study atmospheric processes under clean, natural conditions comparable to pre-industrial times. For this, in-situ and remote sensing instruments observe atmospheric prcesses up to the mesopause.
