Conduct of Cloud Spectra Measurements.

Abstract

THE WORK ADDRESSED THE FOLLOWING OBJECTIVES: Compare bench determinations of Axially Scattering Spectrometer Probe (ASSP) and Forward Scattering Spectrometer Probe (FSSP) sample areas with determinations during actual cloud sampling; Evaluate the accuracy of the overlap in size range between FSSP and 1D-C probes; Evaluate the response of the ASSP and FSSP probes to ice crystals; Check the statistical correction schemes used to deal with 1D-C counts in the lowest and highest size categories. The information needed to accomplish these objectives was collected by performing special tests with the probes in question. These tests were conducted, for the most part, at the Elk Mountain Laboratory, during times when the Observatory was enveloped by clouds. Bench and wind-tunnel tests were utilized. In addition, data were derived from aircraft penetrations of clouds, with identical probes as those used at the Observatory.
