The Design, Development and Test of Balloonborne and Groundbased Lidar Systems. Volume 2. Flight Test of Atmospheric Balloon Lidar Experiment, ABLE 2

This is Volume 3 of a three volume final report on the design, development and test of balloon borne and groundbased lidar systems, Volume 1 describes the design and fabrication of a balloonborne CO sub 2 coherent payload to measure the 10.6 micrometers backscatter from atmospheric aerosols as a function of altitude. Volume 2 describes the August 1987 flight test of Atmospheric Balloonborne Lidar Experiment, ABLE 2. In this volume we describe groundbased lidar development and measurements. A design was developed for installation of the ABLE lidar in the GL rooftop dome. A transportable shed was designed to house the ABLE lidar at the various remote measurement sites. Refurbishment and modification of the ABLE lidar were completed to permit groundbased lidar measurements of clouds and aerosols. Lidar field measurements were made at Ascension Island during SABLE 89. Lidar field measurements were made at Terciera, Azores during GABLE 90. These tasks have been successfully completed, and recommendations for further lidar measurements and data analysis have been made.
