Summary
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 ...

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. Level-3 automatic QA procedures involve simply evaluating the Level-2B quality flags to determine if observations are valid for Level-3 products.
