Abstract The current data quality control standard has not set the maximum allowable change range for the time coherence check of wind direction data.By comparing and analyzing the minute data of the wind direction of the new station and the data of two sets of wind direction sensors under the same observation environment,this paper determines the reasonable maximum allowable change threshold of wind direction change,and analyzes the reasons for the large difference.The research results provide a reference for improving the quality control method of observation data.
