基于辐射传输模式的中国典型区域大气样本库特征分析

在对中国区域北京、哈尔滨、杭州、昆明、拉萨、三亚、西宁7个代表站逐日探空资料进行质量检验的基础上，对其中1、4、7、10四个月(分别代表4个季节)的探空资料进行了大气温湿廓线的特征分析，同时又与目前国际上用于辐射传输计算的43条温湿廓线进行了简单的对比。结果表明，中国区域的大气廓线有明显的时间、空间分布特征，与海拔高度之间联系不大；仅用国际通用的温湿廓线进行我国区域的卫星正演、反演计算有其缺陷性，必须将具有我国天气、气候特征的大气样本补充进去。所收集样本可用于计算大气透射率、反演的初估场及反演结果的真实性检验等。

Characteristics Analysis of Atmospheric Profile Database in Representative Regions in China Based on Radiative Transfer Model

A quality verification of the day to day radiosonde data of seven stations from May 2002 to April 2003 was conducted and a characteristics analysis was made of temperature and water vapor profiles from radiosonde data in January, April, July and October. Theses profiles were compared with 43 profiles used frequently worldwide in radiative transfer calculation. The results show that atmospheric profiles in China have obvious temporal and spatial distribution characteristics and have little relation with altitude. It is not enough to use the universal 43 profiles in the forward and retrieval calculations in China, so samples from China should be added.
