12 January 2005 GroundWinds balloon fringe-imaging Doppler lidar mission concept and instrument performance
Author Affiliations +
Over the past few years, the GroundWinds program has produced two operational, ground based, multi-order fringe imaging direct detection Doppler wind LIDARs. The two existing instruments are located in Bartlett, NH and Mauna Loa, HI and operate at a wavelength of 532 nm and 355 nm, respectively. Both systems employ Fabry-Perot etalons as the wavelength resolving element and are capable of detecting Doppler shifts in both Aerosol and Molecular backscatter from 0.25 km to 18 km. Patented technologies demonstrated and developed through this program, such as Photon-Recycling (U.S. patent #6,163,380) and the Circle To Line Optic (U.S. Patent #4,893,003), will be incorporated into the next generation interferometer design and flown on a high altitude (30km) balloon. The opportunity to view the entire troposphere from a downward looking high altitude platform will serve as an empirical reference point for scaling to space. This paper will discuss the BalloonWinds mission concept and top-level specifications of the instrument subsystems. Additionally, this paper will report on the testing and progress of the instrument build and present performance projections based on the as built system.
