Uncertainty Evaluation of Wind Speed Sensor in Automatic Weather Station

Abstract

Abstract Uncertainty is a description of the degree of uncertainty of measurement results affected by measurement errors. This article completes the repeatability test of the verification results according to “JJG (Meteorology) 004-2011 Automatic Weather Station Wind Speed and Direction Sensor Verification Regulations”. The author establishes a mathematical model to determine the source of uncertainty, calculates the uncertainty components item by item, and completes the analysis of the verification results of the anemometer standard device. This helps to ensure the reliability of the observation data of the meteorological wind speed sensor.
