HALO
High Altitude Lidar Observatory

The High Altitude Lidar Observatory (HALO) is a multi-function airborne lidar used to measure profiles of water vapor, methane, and aerosols. HALO uses a combination of DIAL (DIfferential Absorption Lidar) and HSRL (High Spectral Resolution Lidar) techniques to generate these profiles. HALO provides measurements using three different laser transmitters (1645 nm, 1604 nm, 935 nm) and single multi-channel and multi-wavelength receiver.
