The Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) instrument on the NASA EOS Aqua satellite provides global passive microwave measurements of terrestrial, oceanic, and atmospheric variables for the investigation of global water and energy cycles.
These near real-time (NRT) products are generated within 3 hours of the last observations in the file, by the Land ... Atmosphere Near real-time Capability for EOS (LANCE) at the AMSR-E Science Investigator-led Processing System (AMSR-E SIPS). The AMSR-E/Aqua Level 3 12.5 km daily sea ice product includes 18.7 - 89.0 GHz TBs, sea ice concentration averages (asc & desc), and 5-day snow depth over sea ice on a 12.5 km polar stereographic grid, generated by the NT2 algorithm using Level-2A TBs. Data are stored in HDF-EOS format, and are available via FTP from the LANCE system.
If data latency is not a primary concern, please consider using science quality products. Science products are created using the best available ancillary, calibration and ephemeris information. Science quality products are an internally consistent, well-calibrated record of the Earth's geophysical properties to support science. Science quality AMSR-E products are available from NSIDC DAAC.
