Abstract. The study of precipitation at very high latitudes is challenging because of the harsh environmental conditions that limit the external activity of humans and instruments, particularly during the polar winter. I describe a device (ICE-CAMERA) for automatic imaging, measuring and classifying ice precipitation on the high plateau. From 2014 the instrument operates unattended, all year round, at Concordia Station (75° S,123° E, 3220 m altitude). The instrument provides detailed precipitation information every hour. The article describes the apparatus and its treatment software.

Short summary
Any instrument on the Antarctic plateau must cope with a harsh environment. Concordia station is a special place for testing new instruments: with low temperatures and weak winds, precipitation can be studied by simply collecting it on horizontal surfaces. This is typically done manually. ICE-CAMERA is intended as an automatic alternative. The combined construction of rugged equipment for taking photographs of particles and the adoption of machine learning techniques have served this purpose.
