Airborne Remote Sensing Measurements With a Pulsed CO2 Dial System
A lidar instrument based on compact, pulsed carbon dioxide (CO2) lasers has been developed for airborne remote sensing of atmospheric trace species at infrared wavelengths. It was designed for differential absorption lidar (DIAL) measurements using backscatter of laser pulse energy from the ocean and terrain surface in order to infer trace specie column content. The instrument is now operational on the NASA/Wallops Flight Center P3 aircraft. A flight test program started in July 1981 has produced results on instrument performance, backscatter data statistics, and target signatures. We will present these results and discuss their implications for remote sensing with this type of instrument.
