Helicopter-borne thermal infrared sea ice surface temperature maps during the MOSAiC expedition, png format

The surface temperature maps are provided for 35 flights between 02.10.2019 and 23.04.2020 during the MOSAiC expedition. There is one file for every flight. The flights can be identified by the event-related Device Operation label or Flight ID. Surface temperature maps are an advanced data product based on the surface temperature images from each flight. The maps are gridded to an equidistant grid. These displayed maps give a quick overview of the processed data, which are available in NetCDF format as another data type of this data set. The surface temperature is derived from the measured brightness temperature with a constant emissivity of 0.996. Additionally, the time-fixed surface temperature is shown, which is corrected by the temporal temperature drift during each flight. The data are displayed in relative coordinates referenced to the position of RV Polarstern.
