Abstract:
In order to ensure the accuracy, reliability, and comparability of the platinum resistance ground temperature sensors, it is very important to calibrate the temperature sensors of automatic meteorological stations. Through tests, the errors are controlled within the scope of the system permit. Uncertainty analysis is one of the important steps to examine the credibility of calibration results. On the basis of the related operating guidelines about ground temperature sensors of automatic meteorological stations and the evaluation and expression of uncertainty in measurement, ten repeatability tests are conducted, and the sources of the uncertainty in the process of verification are analyzed, targeted to different sources of the uncertainty evaluation of categories A and B. The evaluation method is of certain significance to the credibility evaluation of ground temperature sensor calibration results of automatic meteorological stations
