Air quality -- Environmental meteorology -- Part 3: Ground-based remote sensing of wind by continuous-wave Doppler lidar
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 based on standard atmospheric conditions. This document describes the determination of the line-of-sight wind velocity (radial wind velocity).
NOTE Derivation of wind vector from individual line-of-sight measurements is not described in this document since it is highly specific to a particular wind lidar configuration. One example of the retrieval of the wind vector can be found in ISO 28902-2:2017, Annex B.
This document does not address the retrieval of the wind vector.
This document can be used for the following application areas:
— meteorological briefing for e.g. aviation, airport safety, marine applications, oil platforms;
— wind power production, e.g. site assessment, power curve determination;
— routine measurements of wind profiles at meteorological stations;
— air pollution dispersion monitoring;
— industrial risk management (direct data monitoring or by assimilation into micro-scale flow models);
— exchange processes (greenhouse gas emissions).
This document can be used by manufacturers of monostatic CW Doppler wind lidars as well as bodies testing and certifying their conformity. This document also provides recommendations for users to make adequate use of these instruments.
