中文摘要: 受各种因素的影响，卫星反演大气成分的数据质量存在一定的误差和不确定性，系统和全面的验证工作是获得准确可靠的卫星数据的一个重要组成部分。卫星观测资料的验证主要涉及反演算法中所用的输入参数和卫星反演产品的直接验证这两个部分的内容。本工作以对流层NO2卫星资料验证的需求出发，对当前中国大气本底站的观测现状进行评述，讨论了大气本底观测站在卫星资料地基验证中可能起到的作用和不足之处。区域本底站近地面准确的观测结果和良好的区域代表性有利于对卫星资料的验证，加强地基上对大气物理和化学特性的垂直探测有助于对卫星资料进行准确和定量验证。因此，有必要加强对有利于验证工作的新技术和仪器设备预先进行技术贮备。

Abstract:Affected by various factors, there exist certain errors and uncertainties during the retrieval of atmospheric compositions from satellite data. Systematic and comprehensive validation work is very important to obtain accurate and reliable satellite data. The validation of satellite data is mainly related to two parts of contents: one is the validation of the input parameters used in the retrieval algorithm, and the other is the direct validation of satellite retrieval products. In the work, we firstly reviewed the validation demands when obtaining the tropospheric NO2 satellite data and the current status of the atmosphere background observation stations in China, and then discussed the role of the latter might play in satellite data validation. Accurate surface observations at regional background stations and their good regional representations are beneficial for the validation of satellite data. The capability of vertical measurements of atmospheric physical and chemical properties can strengthen the ability for the accurate and quantified validation of satellite data. Therefore, we strongly recommend that some new technologies and technical equipments which can help the validation work should reserve in advance.
