  • Airborne measurements of directional reflectivity over the Arctic marginal sea ice zone 
    Becker, Sebastian; Ehrlich, André; Jäkel, Evelyn; Carlsen, Tim; Schäfer, Michael; Wendisch, Manfred (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract. The directional reflection of solar radiation by the Arctic Ocean is mainly shaped by two dominating surface types: sea ice (often snow-covered) and open ocean (ice-free). In the transitional zone between them, ...
  • Measurements and Modeling of Optical-Equivalent Snow Grain Sizes under Arctic Low-Sun Conditions 
    Jäkel, Evelyn; Carlsen, Tim; Ehrlich, André; Wendisch, Manfred; Schäfer, Michael; Rosenburg, Sophie; Nakoudi, Konstantina; Zanatta, Marco; Birnbaum, Gerit; Helm, Veit; Herber, Andreas; Istomina, Larysa; Mei, Linlu; Rohde, Anika (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The size and shape of snow grains directly impacts the reflection by a snowpack. In this article, different approaches to retrieve the optical-equivalent snow grain size (ropt) or, alternatively, the specific surface area ...
  • The North Atlantic waveguide and downstream impact experiment
