Abstract:

Work was conducted on the design, construction and testing of instrumentation for the study of day and night airglow phenomena. Descriptions are given of rocketborne instruments used for the measurement of day airglow. For daytime emissions, preliminary results indicate intensities of 500 rayleighs for the 5577A OI line, 1.5 kilorayleighs for the 5893A NaI doublet and less than 2 kilorayleighs for the 6300A OI line. Several special studies are presented on the night airglow data available, particularly in regard to the 5577A and 6300A line emissions. Description is given of a portable, batteryoperated filter photometer for the measurement of night air-glow emissions. It was designed as the data collecting device for the various stations required for a study of the latitudinal variation of night sky emissions. In the case of both day and night airglow photometers, the required calibration procedures were developed along with the design and development of the instruments. A procedure for performing the calibrations and a description of the optical dark room facility are given. Author
