Second generation Global Imager 4 High Resolution AMSR-E 89 GHz Sea Ice http://iup.physik.uni- bremen.de/iuppage/psa/2001/amsrop.html Daily sea ice maps are provided by a small group at University of Bremen using data from JAXAs AMSR-E sensor on NASA's Aqua Satellite (since May, 2002).JAXAAqua Satellite The main problem is data access and usability : NSIDC may have all the best data but it is hard to find. The differences between NASA group and the bootstraps algorithms are confusing The University of Bremen group provides easy to use HDF data of a single variable: ice concentration. The NSIDC AMSR-E datasets have 64 (!) different products, including ice concentration but at lower spatial resolution.
