The Optical IP Camera was mostly observing the snow surface and aligned instruments at the remote sensing site during the MOSAiC expedition in the central Arctic, saving 4K images in JPEG format in 5 minute intervals. Between October to March it was mostly working continuously, while the data from April to September is more sparse. Occasional transects (remote sensing transects) and experiments were recorded in higher acquisition rates. The camera is equipped with high brightness NIR LED spotlights, turning on automatically in low light situations. Over the course of the expedition, the camera had several remote sensing instruments and the snow and ice surface in the field of view and can be used as a supportive dataset for events at the remote sensing site. It was operated always in conjunction with an infrared camera (doi:10.1594/PANGAEA.940717), pointing at the same targets but with a wider opening angle. The same camera model was also attached to the remote sensing hut (doi:10.1594/PANGAEA.939443) during parts of the campaign.
