%X On July 7, 2008, the infrared wide-angle dual-mode line / area array scanner (widas) and Landsat TM were simultaneously observed in the dense observation area of Yingke oasis and huazhaizi desert. The ground data include ASD spectral data, thermal imager data, component temperature, calibration related radiation temperature, canopy continuous temperature, albedo Coverage and CE318 solar spectrophotometer atmospheric parameter data, FPAR, chlorophyll fluorescence. Measurement content:(1) The radiation temperature measured by the thermal imager of the Institute of remote sensing, Chinese Academy of Sciences. The radiation temperature of corn, wheat and bare soil in Yingke oasis was measured. The instrument obtains the component radiation temperature data and takes optical photos in the same field of view at the same time. The shooting height of the thermal imager is about 1.2m.This data includes original data and records, instrument blackbody calibration data. The original data can be processed by using the supporting processing software thermacam research 2001, or the data can be converted into other formats in the software for self programming and reading. The blackbody calibration data of the instrument is stored in Excel format.(2) Albedo data, the measurement object is row sowing corn in Yingke oasis corn field. The measuring instrument includes the voltage value in the upper table and the voltage value in the lower table of the shortwave meter, which is converted into albedo data through the sensitivity coefficient of the meter. The relationship between field radius R and probe height h in the following table is: r = 10h. This data is stored in Excel.(3) ASD spectrometer data. Using the spectrometer (350-1603nm) provided by the Institute of remote sensing of Chinese Academy of Sciences, the spectrum of corn field in Yingke oasis was measured by gray plate. The calibration spectra were measured at the airport by spectrometer, gray plate and black-and-white cloth
