On December 15, the AMSR-E SIPS at GHRC DAAC announced the availability of three near real-time AMSR2 Daily Sea Ice data sets via NASA’s Land Atmosphere Near real-time Capability for EOS (LANCE). These data sets are generated incrementally in near real-time, as data are acquired from the AMSR2 instrument on the Japanese Aerospace Exploration Agency (JAXA) GCOM-W1 satellite. LANCE AMSR2 GIBS Sea Ice imagery will be available in Worldview very soon.
You can access the data at GHRC's LANCE AMSR2 website.
