We intend a 2-week campaign to operate a newly implemented remotely piloted aircraft system (RPAS) for atmospheric state measurements of the lower troposphere. We aim for a combination of transects (max. 5 km) and profiles (max. 2 km, depending on clouds) of key atmospheric parameters of the lower troposphere above varying surface types (snow-covered/glacier vs snow-free tundra vs fjord water). Atmospheric processes impacting and modulating the boundary layer structure are of crucial importance for an enhanced understanding of polar processes as well as their representation in models, and this infrastructure will allow their in situ measurement with high spatial and vertical resolution and across different, previously under-sampled surface types. The added spatial information will also complement- and prove useful for an evaluation of the existing atmospheric observations at the site and allow for a spatial extrapolation.
