%X On July 11, 2008, ground-based simultaneous observations of the Wide-angle Infrared Dual-mode line/area Array Scanner (WiDAS) flight were conducted in the Yingke Oasis and Huazhazi Desert encrypted observation area. WiDAS consists of four CCD cameras, a mid-infrared camera (AGEMA 550), and a thermal infrared camera (S60), and is capable of acquiring data from five angles in the visible/near-infrared (CCD) band, seven angles in the mid-infrared (MIR) band, and seven angles in the thermal infrared (TIR) band simultaneously. Ground data include canopy radiation temperature, vegetation photosynthesis rate, albedo, FPAR, thermal camera data, ASD spectral data, canopy continuous radiation temperature, atmospheric parameters and atmospheric water vapor content data. Measurement content:(1) CE318 Solar Spectrophotometer Atmospheric Parameter Data This dataset is the atmospheric parameters obtained from measurements made by the CE318 solar spectrophotometer at NNU. The measurement location is Hua Zhai Zi desert sample plot 2. The solar spectrophotometer CE318 can inversely perform the optical thickness, Rayleigh scattering, and aerosol optical thickness of the non-water vapor channel through the direct solar radiation measurement data, and the water vapor content of the atmospheric air column can be obtained by the 936 nm measurement data of the water vapor channel, and the horizontal visibility can also be derived from the CE318 data. The CE318 of Beijing Normal University used in this measurement, which can provide the optical thickness in five bands, 1020nm, 936nm, 870nm, 670nm and 440nm, and can be used to invert the atmospheric column water vapor content with the 936nm measurement data. This data includes raw data and processed atmospheric data. The raw data are stored in the CE318 specific file format *.k7, which can be opened by ASTPWin software and accompanied by the description file ReadMe.txt; the processed file includes the optical thickness, Rayleigh scattering,
