We have been studied to measure the atmospheric transparency by the method known as LIDAR. The prototype was developed at AKENO observatory and it had the performance to measure approximately distance exceeding 10km. A new prototype LIDAR system for the Telescope Array (TA) experiment has been developing at Kinki University and first prototype was installed at Black Rock Mesa in Utah, USA. The aim of LIDAR is to determine the atmospheric extinction length within 20 km accurately in desert circumstances based on the result of AKENO experiences. We shall report present. status of atmospheric monitoring system and our future plan in brief.
