Abstract: According to the “standard meteorological observation”, “surface meteorological observation system software operation manual” and relevant technical regulations, some problems were presented at automatic weather stations, problems such as great wind and wind time missing caused by operational software, the duplication unloading of J file data when the collector was switched off and abnormal records when the sensor was replaced. In this paper, these problems are analyzed and addressed. Their relevant processing methods are introduced for the reference of professionals dealing with detection work so as to improve the quality of meteorological data of automatic weather stations and ensure the accuracy, continuity and data integrity.
