ATLAS/ICESat-2 L2A Normalized Relative Backscatter Profiles V007
Listed in NASA Earthdata CMR
ATL04 contains along-track normalized relative backscatter (NRB) profiles of the atmosphere.
Description
The product includes full 532 nm (14 km tall) uncalibrated attenuated backscatter profiles at 25 times per second for vertical bins of approximately 30 meters. Calibration coefficient values derived from data between 13.5 and 11 km above the surface are also included.
The data were acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the ICESat-2 observatory.
