Total Sky Imager observations during POLARSTERN cruise PS122/1 on 2019-11-19

The dataset consist of camera shots of the sky. The camera - a total sky imager manufactured by Canon (Powershot) - was mounted at the top of the Research Vessel Polarstern. At the leg1 (from September until December 2019) of the MOSAIC experiment from Tromsø to the northerns part of the Arctic Ocean this camera shots were taken with a temporal resolution of 15 minutes. The dataset represents the visible projection of weather conditions and cloud cover recorded on the vessel Polarstern in the direction near the zenith. These observations are useful for the interpretation of the atmospheric radiation measurements.
