The data contains upward broadband irradiance, as well as attitude corrected and uncorrected downward irradiance measurements that were performed during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) experiment between June and September 2020. Research flights were conducted by helicopter and the helicopter-borne probe HELiPOD. Measurements were taken by CMP22 broadband pyranometers (210-3600 nm). The data includes the attitude and geographic location of the helicopter/HELiPOD in a 10 Hz temporal resolution.
