| Abstract | The report represents a technical feasibility study of the use of lidar for determining the atmospheric extinction coefficient in low visibility. Measurements were made with three laser sources: a Q-switched ruby laser, a GaAlAs diode laser array, and a modulated cw helium-neon laser. The work, sponsored by the FAA, is part of a program aimed at measuring and reporting slant visibility. Results of lidar measurements made both in natural coastal fog and in artificial fog are analyzed. Extinction coefficients are obtained with the pulsed systems, using both the 'slope' and 'ratio' methods to analyze the backscatter signature. Corrections for finite laser pulse width are included in the data reduction. (Modified author abstract) |
