The NSA-C1 Utqiagvik tower camera is installed at a height of 40 meters above the ground at the topmost boom of the meteorological tower. The camera’s main field of view is directed at the tundra south of the tower, where the 10m Tip Tower is located. The camera captures images of the Tip Tower and the surrounding ground every 30 minutes. Since September 2017, the camera model is the AXIS Q6045-E Mk II PTZ Dome Network Camera. The tower camera images provide a qualitative look at the progression of the seasons at Utqiagvik. The tower camera images are useful for determining the fractional snow or vegetation cover. Additionally, the camera provides a glimpse of on-site weather conditions, showing the changing weather and/or ground conditions.
