Daily Updated AMSR-E Sea Ice Maps

This page presents the AMSR-E sea ice concentrations calculated daily in near real time. The service is part of the GMES project Polar View and of the Arctic Regional Ocean Observing System (Arctic ROOS).

The research for developing, validating and improving the retrieval algorithms is done within the EU Integrated Project DAMOCLES (Developing Arctic Modeling and Observing Capabilites for Long-term Environmental Studies)

Other products updated daily

• Combined MODIS - AMSR-E sea ice maps, snow grain size and soot concentration
• SSM/I sea ice maps

The ASI sea ice concentration algorithm used here has been validated in several studies (Spreen et al. 2005, Spreen et al., 2008).
However, no warranty is given for the data presented on these pages.
