Thus a significant effort was made to obtain calibrated surface pulse reflectance from GLAS measurements. In this paper we describe the calibration and ...
GLAS was designed with sensitive atmospheric lidar channels for cloud and aerosol profiling that could detect all cloud and aerosol layers of optical thickness ...
The derived surface reflectance can be applied for various applications ranging from object classification to identify the presence of the water ice on the ...
This version also computes the 1064 nm optical depth over ice sheets. The assumption is made that over ice sheets, the true surface reflectance is a constant ...
GLAS operates with infrared and visible laser light pulses at 532 nm and 1064 nm wavelengths at eye-safe signal levels. These laser light pulses illuminate the ...

The Geoscience Laser Altimeter System (GLAS) on ICESat was build to transmit short pulses (4 ns) of infrared light (1064 nm) and visible-green light (532 nm).
GLAS has a 1064 nm laser channel for surface altimetry and dense cloud heights, and a 532 nm lidar channel for the vertical distribution of clouds and aerosols.

To test current understanding of ocean reflectance we compare surface pulse returns measured with the 1064 nm altimetry channel of the Geoscience Laser ...
A 300-W average power diode-pumped, Q-switched Nd:YAG laser generates 40 pulses per second of both 1064-nm infrared (IR) and 532-nm green radiation. Each 5-ns- ...
