AMSR-E/Aqua 89 MHz sea ice images

View daily images of Arctic sea ice. Data are provided by the National Snow and Ice Data Center in Boulder. The 89 MHz horizontal/vertical brightness temperature retrievals show the location and movement of multi-year sea ice, indicated by low values. The horizontal/vertical brightness temperature difference plots show the location of all types of sea ice with areas of partially or completely open water, indicated by high values.

Maximum surface brightness temperature

These images are updated once per day, based on the Arctic Composite images, and indicate the maximum brightness temperature experienced by a location over the past 2, 4, 6 or 8 days. The 6 and 8 day integrations typically result in cloud-free views of the surface of the Earth.
