Abstract
The GroundWinds direct detection Doppler wind LIDARs located in NH and HI are operational, ground based, multi-order fringe imaging systems capable of detecting Doppler shifts in both Aerosol and Molecular backscatter from 0.25 km to 18 km. The technology developed through these GroundWinds programs will be incorporated and flown on a high altitude (30km) balloon in 2005. The demonstration of GroundWinds Fabry-Perot based incoherent LIDAR technology from a high altitude, downward looking platform to measure winds throughout the entire troposphere and boundary layer will be a significant milestone toward the validation of this technology. Key questions will be answered about the phenomenology of direct detection LIDAR, especially its effectiveness in the optically thick boundary layer. The extensive characterization of the 532nm GroundWinds NH and 355nm GroundWinds HI LIDARs serve as excellent reference points from which performance estimates and technology requirements can be determined to ensure a successful balloon mission. This paper will describe the baseline BalloonWinds instrument specifications; including etalon specifications, system component transmissions, transmit/receive specifications, required laser power, and detector characteristics. This paper will also present performance estimates based on model simulations that employ the baseline system specifications.
