Evaluation of an Aureole Lidar Technique for Estimating Extinction Profiles.

摘要

An aureole lidar technique for estimating extinction profiles was developed at the Naval Research Laboratory, Washington, DC. This technique was evaluated by making nearly simultaneous measurements of atmospheric extinction from the NRL airborne Aureole Lidar Platform and the NOSC Airborne Platform, which utilizes the Particle Measuring Systems (PMS), Inc., aerosol spectrometers. Profiles of measured aerosol-size distributions were used to calculate extinction coefficients and were compared with the aureole lidar estimations. Aureole lidar estimated extinction coefficient profiles are similar in structure to the PMS-measured profiles and agreed well in extinction magnitude. When the near-surface aircraft aerosol measurements are averaged over a longer time, excellent agreement exists between the aureole lidar and the PMS-measured values. atmospheric optics lidar optical propagation atmospheric aerosol extinction
