Laser Risk Reduction Program (LRRP)

Laser / Lidar remote sensing techniques satisfy a variety of measurement requirements for Earth science, as well as for space science, space exploration, and aeronautics. Lasers allow remote sensing of earth-system variables such as sea elevation, atmospheric composition, wind profiles, cloud cover, ice mass, and vegetation canopy.

The Laser Risk Reduction Program was established in 2001 by ESTO in order to formalize design, testing, and development procedures for durable laser systems and architectures, particularly in the critical 1- and 2-micron wavelengths. LRRP aimed to demonstrate laser technologies that could be reliably and confidently applied to a wide range of applications. Many LRRP projects have found their way into formal Earth observing instruments and systems. 35 LRRP projects were completed by 2010 when program funding ended.
