Lidar laser radar data obtained under conditions of low ceiling and visibility are analyzed by hand and by electronic computer to explore the operational utility of lidar in cloud ceiling and visibility determination for aircraft landing operations. Hand analyses of the data show the ability of the lidar to describe the spatial configuration of the low-cloud structure with respect to touch-down point. The problems inherent in evaluation of lidar observations are discussed, and initial approaches to quantitative solutions by computer are presented. It is demonstrated that operationally useful information on the ceiling and visibility conditions contained in the hand analyses can be presented by digitizing the lidar data and subjecting these data to computer analysis.
