LRO MOON LASER ALTIMETER 3 RADR V1.0

Published by National Aeronautics and Space Administration | National Aeronautics and Space Administration | Metadata Last Checked: August 04, 2025 | Last Modified: 2025-07-17
This data set contains archival radiometric data derived from reduced altimetry measured by the Lunar Orbiter Laser Altimeter instrument during LRO's Nominal Mission. LOLA is a pulse detection, time-of-flight laser altimeter that measures the distance between the LRO spacecraft and the surface of the Moon. LOLA transmits a 5-spot pattern, thus providing 5 simultaneous profiles across the lunar surface whose separation depends on spacecraft altitude. LOLA also measures the energy of the return pulses, which enables the calculation of the surface albedo after calibration.
