过冷雾驱散项目的设计、运行与评估标准 PDF下载

该标准由 ASCE 环境与水资源研究所(EWRI)编制,2020 年发布,最新重印版为 2025 年(ASCE/EWRI 44-20(R2025)),共约 43 页。其核心内容包括:

适用范围
为机场、港口、公路、风电场等需要消除或减轻过冷雾(supercooled fog)影响的工程,提供一套从可行性研究、方案设计、运行实施到效果评估的全流程技术指南。
关键技术路线
气象监测:利用地面观测、卫星、雷达及探空资料识别过冷雾层厚度、液态水含量与过冷水滴谱。
播撒设计:给出碘化银(AgI)或液态丙烷(LP)播撒剂量、高度、间距及作业时机计算式。
运行安全:规定空域审批、播撒记录、人员培训、环境影响与应急预案。
效果评估:采用能见度提升率、液态水含量下降率、运行延误减少率三项指标进行统计检验。
主要用途
供机场管理局、航空公司、公路运营单位、气象服务公司和环保咨询机构在策划雾驱散项目时直接引用,也可作为政府审批部门的评审依据。
