Development of atmospheric transparency measurement device for the Telescope Array experiment

Abstract

The atmospheric transparency measurement for the Telescope Array (TA) experiment in Utah, USA is done by using LIDAR system and CLF system that use the pulse laser (355 nm). The LIDAR system observes the backscattering light of the laser, and the CLF system observes the side scattering light. The consistency of the time variation of an atmospheric transparency was confirmed into the observation method and the analysis in both systems.
