摘　　要：针对传统探空数据与COSMIC掩星数据拟合度分析问题,文中利用2010年春夏秋冬不同季节数据进行比对,旨在分析COSMIC掩星与无线电探空仪探测数据的拟合度。结果表明,不同季节COSMIC掩星反演大气廓线温度探测精度与传统探空数据高度拟合,温度偏差值浮动与季节无关。因此,COSMIC掩星数据大气湿温廓线探测精度可靠,可应用于大气领域研究。Aiming at the problem of the fitting degree analysis between the traditional radiosonde data and COSMIC occultation data,in this paper,the data of different seasons in spring,summer,autumn and winter in 2010 was compared to analyze the fitting degree between COSMIC occultation data and the radiosonde data.Results showed that the detection accuracy of atmospheric profile temperature retrieved by COSMIC occultation in different seasons was highly fitted with the traditional radiosonde data,and the fluctuation of the temperature deviation was irrespective of the seasons.Therefore,the detection accuracy of atmospheric wet temperature profile of COSMIC occultation data was reliable,which could be used in atmospheric research.
