About half of airliner accidents in Japan occurred in the decade between 2003 and 2012 is related to air turbulence. To contribute flight safety, JAXA proceeds with development of an airborne Doppler LIDAR (Light Detection and Ranging) that can detect air turbulence in clear weather condition. Even if the Doppler LIDAR has an enough observation range on the ground, its observation range comes to be shortened at high altitude, because the intensity of scattered laser light is low due to the low density of aerosol particles. The JAXA's newest model of LIDAR has a capability to observe air turbulence at a distance of more than 30 km on the ground. The LIDAR was installed on a jet aircraft and the observation capability was evaluated at high altitude. Consequently, the observation range of more than 9 km was verified. Development of the LIDAR and the test result are explained.
