保证现场测量离水辐射率精度的关键工作之一是对现场测量设备进行严格的实验室定标。本文就 1 999年 9月进行的一次实验室绝对辐射定标试验 ,简述辐照度、辐亮度定标的主要方法及数据处理方法。
One of the key tasks to ensure on-site measurement of emissivity from water is to conduct rigorous laboratory calibration of field measurement equipment. In this paper, a laboratory absolute radiation calibration experiment was conducted in September 1999, and the main methods and data processing methods of irradiance and radiance calibration were briefly described.
