General Description:

The Gulfstream V High Spectral Resolution Lidar (GV-HSRL) is an eye-safe calibrated lidar system that measures cloud and aerosol back scatter coefficient and depolarization ratio. It can also measure cloud extinction and optical depth.

The instrument was originally designed and built by the University of Wisconsin Lidar Group. The instrument had successful test flights on the NSF/NCAR GV in Feb 2010 and was delivered to NCAR in the summer of 2010. The instrument had its first field deployment on the NSF/NCAR GV in TORERO in January and February 2012 and has been deployd in two additional aircraft field projects since then (CSET and SOCRATES). When not deployed in field on the GV aircraft the instument operates from the lidar lab or lidar seatainer in Boulder Colorado.

Measurement Characteristics:

Wavelength: 532 nm

Minimum Range: 350 m

Maximum Range: 10 km or cloud attenuation

Sampled Range Resolution: 7.5 m

Sampled Time Resolution: 0.5 sec

Lidar typically cannot penetrate liquid water and mixed phase clouds beyond a few 10s of meters. Ice cloud penetration is typically 1-4 km depending on the cloud density.

Calibration Methods:

The HSRL technique uses an independent backscatter channel that observes only molecular scattering to act as a calibration target at each range bin. This allows the retrieval to remove effects of the instrument and atmospheric transmission in backscatter coefficient retrievals. The molecular backscatter is also leveraged to obtain an estimate of extinction.
