Abstract:	Surface temperature maps, gridded in 1 m resolution, 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. The surface temperature maps are an advanced data product based on the surface temperature images from each flight. The images are gridded to an equidistant grid. These gridded surface temperatures are available for a quick look in png 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 included, which is corrected by the temporal temperature drift during each flight. All data are ice drift corrected and georeferenced, and provided with longitude and latitude coordinates as well as relative coordinates referenced to the position of RV Polarstern.
