NRT AMSR-E/Aqua L2A Global Swath Spatially-Resampled Brightness Temperatures (Tb)Entry ID: AE_L2A_NRT
Abstract: 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-2A swath product includes brightness temperatures at 6.9 GHz, 10.7 GHz, 18.7 GHz, 23.8 GHz, 36.5 GHz, and 89.0 GHz resampled at resolutions of 56 km, 38 km, 21 km, 12 km, and 5.4 km. 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 Earth¹s geophysical properties to support science. Science quality AMSR-E products are available from NSIDC DAAC.

Quality Differences between the LANCE NRT and standard products are currently under investigation. Known, but not yet quantified, differences include
• the ephemeris files (LANCE uses predicted ephemeris and standard products use definitive ephemeris) and
• standard product generation includes more sophisticated, dynamic cross calibration and geolocation processes.
