381	Quantitative interpretation of laser ceilometer observations Lamoureux, Marie-France, 1972- January 1996 (has links) This is a study of various methods for the analysis of the returned power measured by a laser ceilometer. The calibration constant of the ceilometer is computed, and used to solve for atmospheric optical extinction profiles, in various cases of haze and precipitation. Other methods of analysis, requiring simultaneous measurements with a UHF boundary layer profiler, are also used to find extinction profiles. A comparison between the extinction profiles found using the different analysis techniques is provided. The results indicate that the method of solution that uses the calibration constant of the ceilometer is the most accurate. This work is not a comprehensive study of all the different methods of solving for optical extinction profiles using ceilometer and radar measurements, although it provides solid groundwork for future research.
