Statistical Analyses of Dual-Band Infrared Cloud Imagery

Abstract

A dual-band comparison in the SWIR and LWIR atmospheric windows was made of the spatial, temporal, and radiometric statistics of clouds as observed by the Ground Based Measurements (GBM) Sensor of the Army Optical Station. The existence of the GBM archives has provided a unique opportunity to analyze the properties of cloud images simultaneously observed in the 3-5 and the 8-12 micron passbands. It is shown that the level of correlation in clutter between the two passbands is a strong function of the meteorological conditions. Through observations of reentry vehicles passing behind clouds, point measurements of the attenuation of target signature, have been achieved.
