Abstract In order to study the uncertainty assessment of the calibration results of ARC100 rainfall calibrator,the main sources of uncertainty were determined by analyzing the measurement principle and calibration method of the calibrator.Use appropriate evaluation methods to quantify and synthesize each uncertainty component.The results indicate that the uncertainty of the ARC100 rainfall calibrator during the calibration process is mainly affected by factors such as instrument accuracy,environmental conditions,and operators.The research results provide a theoretical basis for improving the measurement accuracy of rainfall calibrators and provide reference value for research in related fields.
