NCAR HSRL Request Guidance Information

HSRL Overview
The NCAR High Spectral Resolution Lidar (HSRL) is an eye-safe calibrated lidar system that can measure backscatter cross-section, extinction, and depolarization properties of atmospheric aerosols and clouds. The system can be deployed on the NSF/NCAR HIAPER GV aircraft. It is installed in the front of the GV cabin and occupies slots for four instrument racks. The lidar points either up or down (in the aircraft coordinate frame) and can be changed during flight.

Number of available systems: 1
Configuration: NSF/NCAR HIAPER GV aircraft
Not available for ground based operations. See MPD for ground based HSRL options.
