AB  - The ground synchronous observation data include ASD spectrometer data, Lai, photosynthetic rate, FPAR, albedo, radiation temperature, coverage and CE318 solar spectrophotometer atmospheric parameters data. On June 1, 2008, the ground synchronous observation of airborne wide-angle infrared dual-mode line / area array scanner (widas) was carried out in Yingke oasis and huazhaizi desert intensive observation area. Widas is composed of four CCD cameras, a mid infrared thermal imager (AGEMA 550) and a thermal infrared thermal imager (S60). It can simultaneously obtain data of 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.  Measurement content:(1) Radiant temperatures obtained from thermal camera ThermaCAM SC2000 measurements. Measurements were made on corn, wheat, and bare soil in the cornfield of the PCG Oasis and on radiation temperatures in sample plot 1 of the Huazhazi Desert. The instrument acquired radiant temperature data with a field of view of 24° x 18° components and simultaneously took optical photographs of the same field of view. The height of the thermal camera shot was approximately 1.2 m. This data includes raw data and records, instrument blackbody calibration data. Raw data can be utilized with the supporting processing software ThermaCAM Researcher 2001, or the data can be converted to other formats in this software and programmed to read by themselves. The instrument blackbody calibration data is stored in Excel format. (2) Radiation temperature data measured by fixed self-recording point thermometer. The infrared radiation temperature data of the corn field in Yingke Oasis were measured continuously using the Fixed Self-Recording Point Thermometer No.1 of Remote Sensing Institute of Chinese Academy of Sciences. The field of view of the instrument was about 10°, vertical downward observation, and the sampling interval was higher than 1 s. The heigh
