This animation shows the daily sea ice surface temperature over the northern hemisphere from September 2002 through May 2003. The sea ice surface temperature was measured by the MODIS instrument on the Aqua satellite. Since this instrument cannot take measurements through clouds or in the dark, in dark or cloud-covered regions or areas with suspect data quality, the prior day's value is retained until a valid data reading is obtained. The color of the sea ice indicates the sea ice surface temperature.
This color bar shows the colors used to represent the sea ice surface temperature. The coldest water is shown in light blue. The warmest sea ice is shown in shades of pink. As the sea ice surface temperatures cool below -15 degrees Celsius, the color is shown in shades of purple. The sea ice surface below -28 degrees Celsius is shown in shades of blue and grey.
