Abstract

The Pennsylvania State University, Department of Electrical Engineering and Applied Research Laboratory, University Park, Pennsylvania, U.S.A.

The Lidar Atmospheric Profile Sensor (LAPS) instrument is capable of simultaneously measuring profiles of ozone, water vapor, temperature, and optical extinction. Tue measured profiles are integrated, for user selected intervals, to calculate and display the real-time atmospheric profiles with their associated errors, ± 1 a standard deviation. Profiles of ozone are obtained from a Differential Absorption Lidar (DIAL) analysis of the Raman shifted scatter of N₂ and 0₂. The LAPS instrument uses the "solar blind" portion of the ultraviolet spectrum to obtain measurements during daytime periods when large background limits visible measurements.
