Precipitation is among the most important meteorological variables for, e.g., meteorological, hydrological, water management and climate studies. In recent years, non-catching precipitation gauges are increasingly adopted in meteorological networks. Despite such growing diffusion, calibration procedures and associated uncertainty budget are not yet standardized or prescribed in best practice documents and standards. This paper reports a metrological study aimed at proposing calibration procedures and completing the uncertainty budgets, to make non-catching precipitation gauge measurements traceable to primary standards. The study is based on the preliminary characterization of different rain drop generators, specifically developed for the investigation. Characterization of different models of non-catching rain gauges is also included.
降水是气象学、水文学、水资源管理和气候研究等领域最重要的气象变量之一。近年来，非接雨式雨量计在气象网络中得到了越来越多的应用。尽管这种应用日益普及，但校准程序和相关的不确定度预算在最佳实践文件和标准中尚未标准化或规定。本文报告了一项计量学研究，旨在提出校准程序并完成不确定度预算，使非接雨式雨量计的测量结果可追溯到主要标准。该研究基于对专为该研究开发的不同雨滴发生器的初步特性描述，同时还包括对不同非接雨式雨量计模型的特性描述。
