Paper Abstract

With two sets of experimental instruments, laser transmission was investigated through horizontal atmosphere at 1.06 m under fine and haze-fog events. One set of the instruments is an indirect transmission meter used to measure visibility and the other one is a direct transmission meter used to measure the attenuation of laser power. Results show that the variation of transmittance got from laser power (Tp) and that obtained by visibility (Tvis) are highly correlated. For relative humidity (RH) below 85%, the curve of Tvis fits that of Tp very well. While the RH is above 85%, the Tvis is more likely smaller than Tp under fine meteorological condition, but under haze-fog condition Tvis is larger than Tp on the contrary. For different weather condition, the relation efficient between extinction coefficient and visibility is different. Even for similar visibility, the extinction coefficient of haze-fog event is larger than that of fine event.
