标准摘要
[中文适用范围]： 本文档规定了使用实验室装置，基于对流层高层温度下的相对湿度水平变化，对从批量生产批次中抽样的无线电探空仪湿度传感器进行校准误差测定的测试程序。本文档提供：a) 用于评估无线电探空仪湿度测量校准误差的实验室装置的技术要求；b) 在温度范围为-90°C至35°C、相对湿度范围为1%rh至100%rh内评估无线电探空仪湿度传感器校准误差的测试程序（注意：本文档基于水汽压除以液态水饱和水汽压的百分比计算相对湿度，即使温度低于0°C也不使用冰面，因此低于0°C时最大相对湿度小于100%rh）；c) 评估测量的无线电探空仪湿度校准误差不确定度的方法。 [外文原描述]： The document specifies testing procedures for determining calibration error for radiosonde humidity sensors sampled from mass production batches based on varying the levels of relative humidity at atmospheric upper-air temperatures using a laboratory setup. This document provides: technical requirements for a laboratory setup to evaluate the calibration errors of radiosonde humidity measurement; a test procedure for evaluating calibration error of radiosonde humidity sensors for a temperature range 1) of −90 °C to 35 °C and for a relative humidity of 1 %rh to 100 %rh. Note, this document, is based upon relative humidity calculated by the percentage of water vapour pressure divided by saturation water vapour pressure over liquid water, not over ice, even at temperatures below 0 °C; hence, the maximum relative humidity is less than 100 %rh below 0 °C; a method for evaluating the uncertainty for the measured radiosonde humidity calibration errors. 1) Currently, the lowest possible temperature of commercially-available climate chambers is approximately -75 °C. The temperature range can be adjusted based on the capability of the climate chamber used.
