空气质量.环境气象学.第3部分:用连续波多普勒激光雷达对风的地面遥感

[中文适用范围]： 本文件规定了单基地异差连续波 (CW) 多普勒激光雷达技术的要求和性能测试程序，并介绍了其优点和局限性。本文件中使用的术语“多普勒激光雷达”仅适用于单基地异差 CW 激光雷达系统，该系统通过大气中的气溶胶对激光的散射来检索风测量值。性能和限值基于标准大气条件描述。本文件描述了视线风速 (径向风速) 的确定。注：本文件未描述从单个视线测量中推导出风矢量的方法，因为它特定于特定的风激光雷达配置。可以在 ISO 28902-2:2017，附件 B 中找到一个检索风矢量的示例。本文件不涉及风矢量的检索。本文件可用于以下应用领域： — 气象简报，例如航空、机场安全、海洋应用、石油平台； — 风力发电，例如场地评估、功率曲线确定； — 气象站风廓线的常规测量； — 空气污染扩散监测； — 工业风险管理（直接数据监测或通过微尺度流动模型进行同化）； — 交换过程（温室气体排放）。 本文件可供单站 CW 多普勒风激光雷达制造商以及测试和认证其符合性的机构使用。 本文件还为用户提供了充分利用这些仪器的建议。 [外文原描述]： 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.
