AMSR2 2015 Minimum Arctic Sea Ice Extent

  • Released Thursday, September 10, 2015

The Japan Aerospace Exploration Agency (JAXA) provides many water-related products derived from data acquired by the Advanced Microwave Scanning Radiometer 2 (AMSR2) instrument aboard the Global Change Observation Mission 1st-Water "SHIZUKU" (GCOM-W1) satellite. Two JAXA datasets used in this animation are the 10-km daily sea ice concentration and the 10 km daily 89 GHz Brightness Temperature.

In this animation, the daily Arctic sea ice and seasonal land cover change progress through time, from February 25, 2015 through the 11th of September, 2015, when the ice reaches its annual minimum extent. Over the water, Arctic sea ice changes from day to day showing a running 3-day minimum sea ice concentration in the region where the concentration is greater than 15%. The blueish white colour of the sea ice is derived from a 3-day running minimum of the AMSR2 89 GHz brightness temperature. Over the land, monthly data from the seasonal Blue Marble Next Generation fades slowly from month to month.
