Second Front Range Lidar, Aircraft, and Balloon Experiment

摘要

The first Front Range Lidar, Aircraft, and Balloon (FRLAB) experiment was performed near Boulder, Colorado on July 26, 1989, and the second FRLAB experiment was performed on May 23-24, 1990. The purpose of the experiment was to make simultaneous measurements of aerosol profiles in the atmosphere using CO2, ruby, Nd:YAG, and Er:Glass lidars; airborne nephelometer, condensation nucleus (CN) counter, and aethalometer; and balloonborne backscattersonde. The data allow a direct comparison between several diverse types of instruments as well as a quantitatively consistent evaluation of the amount of non-Rayleigh scattering occurring in the tropospheric clean region where lidar profiles are often normalized.
