In this study we have developed LED mini-lidar for atmosphere measuement. This mini-lidar can follow the steep dynamics of the low atmosphere with the high-speed photon counter. This time, 265nm LED as the solar blind wavelength was installed into the mini-lidar.This DUV wavelength region does not only cause the large scattering crossection of aerozol particles, but also cause the large scattering crossection of atmospheric molecules. This report states theoretical analysis and concrete implementation of the 265nm LED mini-lidar.
