Abstract 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.
