By comparing the data of a set of standard multi-element observation stations with the data of multiple measured traffic stations, the outliers of each element data at each station were analyzed. It could provide data support for the maintenance of Zhangjiakou traffic meteorological observation station and a guarantee for the accuracy of forest service during Beijing Winter Olympic Games period.展开更多
