Initial version of the processing software
ATL04 contains along-track atmosphere backscatter data at full instrument resolution. The product includes full 532 nm (14 km) uncalibrated attenuated backscatter profiles at 25 times per second for vertical bins of approximately 30 meters. Includes calibration coefficient values derived from data within the polar regions.
The purpose of ATL04 is to provide normalized relative backscatter and ancillary meteorological and atmosphere data that will be used by to create the upstream ATL09 product.
The software that generates the ATL04 product was designed and implemented within the ICESat-2 Science Investigator-led Processing System at the NASA Goddard Space Flight Center in Greenbelt, Maryland.

ATLAS > Advanced Topographic Laser Altimeter System
ATLAS
Advanced Topographic Laser Altimeter System
Laser Altimeter
ATLAS on ICESat-2 determines the range between the satellite and the Earth's surface by measuring the two-way time delay of short pulses of laser light that it transmits in six beams. It is different from previous operational ice-sheet altimeters in that it is a photon-counting LIDAR. ATLAS records a set of arrival times for individual photons, which are then analyzed to derive surface, vegetation, and cloud properties. ATLAS has six beams arranged in three pairs, so that it samples each of three reference pair tracks with a pair of beams; ATLAS transmits pulses at 10 kHz, giving approximately one pulse every 0.7 m along track; ATLAS's expected pointing control will be better than 90 m RMS.
