Abstract

A pulsed direct detection CO2 lidar using the integrated path differential absorption technique has been developed to determine the average CO2 column abundance. The lidar uses a line in the 1570 nm band, 1-µsec wide laser pulses and a photon counting receiver. A new correlation analysis technique is used to estimate the laser pulse time-of-flight from its measurements. Results show it is robust and allows column length (range to the surface) to estimated to <1 m precision for stationary targets in the field and to <3 meters in airborne experiments.
