The automatic weather station is an important component of the automatic weather observation system(AWOS),which mainly collects meteorological factors such as wind speed and direction,atmospheric pressure,temperature and hu-midity,and solar radiation,providing important meteorological data for aircraft flight.The runway of Beijing Capital Interna-tional Airport currently uses three types of automatic weather stations,namely,MAWS310,MAWS301,and MILOS520,pro-duced by Vaisala Corporation.Among them,the MAWS310 automatic weather station is the latest upgraded and used.It is a meteorological data collection system that can automatically measure,process,and store meteorological data for profes-sional use.This paper mainly introduces the system composition,spare parts sensor testing,and maintenance of the MAWS 310 automatic weather station,providing reference for meteorological users to use the automatic weather station.
