NRT AMSR-E/Aqua Daily L3 6.25 km 89 GHz Brightness Temperature Polar Grids
Entry ID:
AE_SI6_NRT
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. Out-of-bounds Level-2A TBs are screened out before TBs are interpolated to the 6.25 km grid.
