Studying precipitation at very high latitudes is difficult because of the harsh environmental conditions that limit the external activity of humans and instruments, especially in the polar winter. The direct monitoring of ice crystal habits and size distribution in Antarctic precipitation is important for the validation of the algorithms used for retrieving precipitation from ground-based and satellite-borne radar instruments and for the improvement of the climatological modelling of polar areas. This paper describes an automated device (ICE-CAMERA) specifically developed for the imaging, measurement, and classification of ice precipitation on the Antarctic high plateau. The instrument gives detailed information on precipitation on an hourly basis. The article provides a description of the device and its image processing software. Starting in 2014, the instrument has operated almost unattended all year round at Concordia station, Antarctica (75 S, 123 E, 3220 m altitude).

由于恶劣的环境条件限制了人类和仪器的外部活动,特别是在极地冬季,研究高纬度地区的降水很困难。对南极降水中冰晶习性和大小分布的直接监测对于验证用于从地面和星载雷达仪器中获取降水的算法以及改进极地地区的气候建模具有重要意义。本文介绍了一种专门为南极高原冰降水的成像、测量和分类而开发的自动化设备 (ICE-CAMERA)。该仪器每小时提供有关降水的详细信息。本文提供了设备及其图像处理软件的描述。从 2014 年开始,南极洲康科迪亚站(75 ∘  S,123  E,海拔 3220 米)几乎全年无人看管。,由于恶劣的环境条件限制了人类和仪器的外部活动,特别是在极地冬季,研究高纬度地区的降水很困难。对南极降水中冰晶习性和大小分布的直接监测对于验证用于从地面和星载雷达仪器中获取降水的算法以及改进极地地区的气候建模具有重要意义。本文介绍了一种专门为南极高原冰降水的成像、测量和分类而开发的自动化设备 (ICE-CAMERA)。该仪器每小时提供有关降水的详细信息。本文提供了设备及其图像处理软件的描述。从 2014 年开始,南极洲康科迪亚站(75 ∘  S,123  E,海拔 3220 米)几乎全年无人看管。
