Air quality. Environmental meteorology - Ground-based remote sensing of wind by continuous-wave Doppler lidar has-tracked-changes conditions and apparatus simulate asWhat is this standard about? This document specifies the requirements and performance test procedures for monostatic heterodyne continuous wave (CW) Doppler lidar techniques and presents their advantages and limitations. The term Doppler lidar used in this document applies solely to monostatic heterodyne CW lidar systems retrieving wind measurements from the scattering of laser light by aerosols in the atmosphere. Performances and limits are described
