| Summary: | An integrated sensor platform including an inertial navigation system (INS) and a commercial (Riegl VQ580) airborne laser scanner (ALS) among other sensor was mounted in the cargo compartment in one of the Polarstern helicopters (D-HARK) during MOSAiC. This sensor combinations allows for a precise mapping of the snow and sea-ice surface around Polarstern at submeter-scale resolution. Information from the ALS data includes the elevation of the snow or ice surface and surface reflectivity at the near-infrared wavelength. From the more than 60 flights acquired between October 2019 and September 2020 we prerelease with this gridded data-set three flights for quality-control and test purposes by potential end users. The geographical coordinates of the data have been corrected for the drift of the sea-ice cover during each survey flight and the elevation bias has been corrected based on overlapping flight transects. Flight dates (Device Operation): Oct. 2, 2019 (PS122/1_2-57) Apr 8, 2020 (PS122/3_35-49) July 22, ... : ALS and INS data was collected as part of the international Multidisciplinary drifting Observatory for the Study of the Arctic Climate (MOSAiC) with the tag MOSAiC20192020 and the Project_ID: AWI_PS122_00. Data processing and analysis is funded by the BMBF IceSense (03F0866A) project. ... |
