Differential Absorption Lidars for Remote Sensing of Atmospheric Pressure andTemperature Profiles

摘要

A near infrared differential absorption lidar technique is developed usingatmospheric oxygen as a tracer for high resolution vertical profiles of pressure and temperature with high accuracy. Solid-state tunable lasers and high-resolution spectrum analyzers are developed to carry out ground-based and airborne measurement demonstrations and results of the measurements presented. Numerical error analysis of high-altitude airborne and spaceborne experiments is carried out, and system concepts developed for their implementation.
