Because of the development of the social economy, people's living standards are also constantly improving recent years. The effect of weather forecast on social economy is more and more important, which has a great influence on agricultural production and personal life. With the advancement of the observation automati-on business, small disturbances may cause systematic errors in observation data. The meteorological observation data's quality is an important factor that directly affects the accuracy of weather forecast and climate forecast. The traditional quality control algorithm uses the climatological limit value of historical data and the allowable value of elements to check, lacks sensitivity to elements fancy changes, and not suitable for demend of quality control. This paper introduces a quality control project of multi-source weather observation based on data mining. Starting from the correlation between the observations of the alike observation element which is not at the same time (time correlation), and the correlation between unlike observation elements at the same time (element correlation), combined with the relevant algorithms in data mining, the paper proposes Two different quality control methods for multi-source meteorological observation data, combined with the complementarity and correlation of the two methods, a synthetic quality control programme is established.
