Paper Abstract

Preliminary experiments toward the implementation of Doppler spectral scanning differential absorption lidar (DSS DIAL) are described. In separate tests, CO2 laser pulses were reflected from either a ground-based retroreflector (36-km round-trip distance) or a retroreflector on the GEOS-3 satellite (approximately 2000-km round-trip distance). The returns were split into a reference channel and an absorptive gas-cell channel. The light was coherently detected with heterodyne receivers and analyzed. Results from the ground-based system produced data that matched expected values in one case but its repeatability remains to be determined. We are currently investigating the satellite-based system to assess the DSS DIAL technique.
