Abstract
An airborne DIAL system with two color pulsed CO2 lasers has been developed for remote measurements of ozone distributions in an urban area. The airborne CO2 DIAL is a nadir-directed and direct range-resolved system, since the system was designed to use aerosols between an aircraft and the ground surface as a distributed target. Flight tests were successfully conducted in September 1986 over Tokyo, Japan, at a flight altitude of 5000 ft (1.7 km). The airborne CO2 DIAL instrument and its first measurements of the vertical profile of urban ozone are described.
