摘　　要：利用2010年6月在内蒙古贡格尔辐射校正场(简称内蒙古辐射校正场)实测的地表反射率和大气气溶胶数据,分析了该辐射校正场的地表反射率和大气气溶胶特性,并与敦煌辐射校正场相关数据进行了对比分析。结果表明:内蒙古辐射校正场地表反射率的相对方差小于5%,表现出较好的均一性;在天气晴朗的情况下,各通道的大气气溶胶光学厚度可达0.1～0.2;内蒙古辐射校正场地理条件优越,交通便利且定标成本低,可作为我国备用的卫星传感器辐射校正场,用于开展卫星传感器的在轨辐射定标及遥感数据真实性检验实验,以进一步提高国产卫星遥感数据定量化应用的可靠性与精度。Using surface reflectance data and atmosphere aerosol data measured at the Inner Mongolia radiometric site in June,2010,this paper analyzed the surface reflectance characteristics,atmosphere aerosol properties and geography conditions and made a comparison between the Inner Mongolia test site and the Dunhuang radiometric calibration site.The results show that the relative deviation of reflectance is less than 5%,indicating that the site has good uniformity,that the aerosol optical thickness of each channel is up to 0.1~0.2 during the fine weather,that the transportation is very convenient and that the cost of the calibration experiment is low.Therefore,the Inner Mongolia radiometric site not only can be used to carry out on-orbit radiometric calibration and validation experiments as the spare radiometric calibration site,but also can improve reliability and accuracy of homemade satellite remote sensing data.
