Surface Imagery based on helicopter-borne observations during MOSAiC

Helicopter-borne surface fisheye imagery taken during MOSAiC. 24 research flights were conducted by helicopter, 5 by HELiPOD, a tow-probe measurement system. HELiPOD research flights can be identified by the name of the respective directory.<br> Black areas indicate masked parts of images due to visible parts of carrier. <br> Images can be used to classify surface into different surface type fractions, as described in Sperzel, T. R. Codes for: Surface Albedo Measurements and Surface Type Classification from Helicopter-based Observations during MOSAiC, https://doi.org/10.5281/zenodo.7974021 (2023).<br> Black masked areas should be considered as such. Results are described in Sperzel, Tim R; Jäkel, Evelyn; Lampert, Astrid; Birnbaum, Gerit; Pätzold, Falk; Neckel, Niklas; Rosenburg, Sophie; Fuchs, Niels; Wendisch, Manfred (2023): Surface type classifications from helicopter-borne imagery during the MOSAiC expedition.
