This is the most recent version of these data.
Overview
The AMSR-E/AMSR2 Unified Level-3 25 km product provides sea ice concentration derived from brightness temperatures using the NASA Team 2 (NT2) algorithm for the Northern and Southern Hemisphere. This data set includes six daily brightness temperature fields for channels ranging from 6.9 through 89.0 GHz, three daily sea ice concentration fields, and three daily sea ice concentration difference fields for ascending orbits, descending orbits, and full orbit daily averages. The sea ice concentration difference fields compare the NT2 algorithm with the Bootstrap algorithm. All fields are mapped to 25 km polar stereographic grids.Note: This product uses the Japan Aerospace Exploration Agency (JAXA) AMSR2 Level-1R input brightness temperatures that are calibrated, or unified, across the JAXA AMSR-E and JAXA AMSR2 Level-1R products.

Many NSIDC DAAC data sets can be accessed using the NSIDC DAAC's Data Access Tool. This tool provides the ability to search and filter data with spatial and temporal constraints using a map-based interface.Users have the option to
To convert HDF5 files into binary format you will need to use the h5dump utility, which is part of the HDF5 distribution available from the HDF Group. How you install HDF5 depends on your operating system.
