The tower camera at the Barrow, Alaska site provides hourly images of ground surrounding the tower. These images may be used to determine fractional snow cover as winter arrives, for comparison with the albedo that can be calculated from downward-looking radiometers, and as an indication of present weather. Similarly, during spring, the camera images show the changes in the ground albedo as the snow melts.
The tower images are saved in hourly intervals. In addition, two other cameras, the skydeck camera in Barrow and the piling camera in Atqasuk, show the current conditions at those sites.
