ISO DIS 28902-3

Description / Abstract: This part of ISO 28902 specifies the requirements and performance test procedures for continuous-wave (CW) Doppler lidar techniques and presents their advantages and limitations. The term “Doppler lidar” used in this standard applies solely to CW lidar systems retrieving wind measurements from the scattering of laser light by aerosols in the atmosphere. A description of performances and limits are described based on standard atmospheric conditions.

This International Standard describes the determination of the line-of-sight wind velocity¹⁾ (radial wind velocity).

This part of ISO 28902 does not address the retrieval of the wind vector.

This International Standard may 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 part of ISO 28902 addresses manufacturers of CW Doppler wind lidars as well as bodies testing and certifying their conformity. Also, this document provides recommendations for the users to make adequate use of these instruments.

¹⁾ Derivation of wind vector from individual line of sight measurements is not described in this International Standard 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, Annex B.
