Lidar Observations at 0.7-micrometers and 10.6 micrometers Wavelengths during Smoke Week II

Abstract

A 10.6-micrometer wavelength lidar and a 0.7-micrometer wavelength lidar (mark IX) were operated to observe smoke and dust clouds. The lidars observed cloud backscatter along horizontal parts that were nearly coincident with those observed by visible and infrared transmissometers operated by the Dugway Proving Ground. The lidar observed paths were terminated with a passive reflector so that time-dependent transmission over the lidar-to-target path could be evaluated from lidar observed target returns. Backscatter signatures for both lidars were digitized and recorded on magnetic tape using the Mark IX lidar data processing system. Recorded lidar data were used to generate intensity-modulated TV displays depicting cloud structure along lidar observed paths as a function of time. These displays were used to choose sixteen Smoke Week II trials for quantitative analysis in terms of cloud attenuation and path- integrated backscatter.
