AMSR-E/Aqua L1A Raw Observation Counts, Version 3
Data set id:
AMSREL1A
DOI: 10.5067/AMSR-E/AMSREL1A.003
This is the most recent version of these data.
Version Summary
The improved V003 AMSREL1A product features empirical corrections to the co-registration parameters A1 and A2, and an updated parameter file used for correcting the AMSR-E 89 GHz position information. As a result, Version 3 AMSREL1A data provide improved accuracy for the following: Latitude and Longitude, land/ocean flags, earth incidence angle, earth azimuth angle, sun azimuth angle, and sun elevation angle. Additionally, the HDF-EOS version was updated from 4.2r1 to 4.2r4.

Overview
