%X Widas (wide angle infrared dual-mode line / area array) was obtained by CE318 solar spectrophotometer in Yingke oasis and huazhaizi desert intensive observation area Scanner, omis-2, TM, aster, Chris and Hyperion, as well as conventional observation of atmospheric parameters provide important atmospheric parameters for atmospheric correction of various remote sensing images and ground measurement data. The original data is stored in CE318 special file format. K7 and can be opened by astpwin software. The preprocessing file includes the retrieval of optical thickness, Rayleigh scattering, aerosol optical thickness, horizontal visibility and near surface atmospheric temperature from the original data, as well as the solar azimuth, zenith angle, sun earth distance correction factor and atmospheric column mass involved in the calculation. Data preprocessing result file includes two parts: data processing description and data processing result. The former introduces the basic principle of data processing, while the latter gives the results of data processing, including "geometric position and total optical thickness of each channel" and "Rayleigh scattering and aerosol optical thickness of each channel".
