Total Sky Imager observations during POLARSTERN cruise PS122/1 on 2019-11-30

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.

本数据集收录了天空场景的相机拍摄影像。拍摄设备为佳能（Canon）Powershot系列全天空成像仪（total sky imager），安装于极地号（Polarstern）科考船顶部。在从特罗姆瑟前往北冰洋北部的MOSAIC实验第一航段（2019年9月至12月）期间，该相机以15分钟的时间分辨率完成了影像拍摄。本数据集呈现了极地号（Polarstern）科考船在近天顶（zenith）方向观测到的天气状况与云覆盖情况的可见光成像结果，该观测数据可用于辅助解读大气辐射测量结果。
