Temporal coverage: 18 June 2002 - 4 October 2011
The Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) "Sea Ice Brightness Temperature (89H and 89V GHz, B Scan)" layer displays sea ice brightness temperatures (TBs) in kelvins at the Polar regions for the 89 GHz horizontal (H) and vertical (V) polarizations for the 1:30 a.m. ascending (day) half-orbit passes of the AMSR-E radiometer B feedhorn. Brightness temperature data are particularly useful for sea ice studies because of the relatively high contrast in emissivities between open water and sea ice.
Onboard NASA's Aqua satellite, the AMSR-E radiometer measured terrestrial, oceanic, and atmospheric parameters used to investigate global water and energy cycles. The imagery resolution is 2 km and sensor resolution is 6.25 km. The temporal resolution was daily.
