AB  - On May 30, 2008, the ground synchronous observation of airborne infrared wide-angle dual-mode line / area array scanner (widas) was carried out in Yingke oasis and huazhaizi desert intensive observation area. Widas is composed of 4 CCD cameras, 1 mid infrared thermal imager (AGEMA 550) and 1 thermal infrared thermal imager (S60). It can simultaneously obtain data of 5 angles of visible / near infrared (CCD) band, 7 angles of mid infrared band (MIR) and 7 angles of thermal infrared band (TIR). The ground synchronous observation data include ASD spectrometer data, Lai, photosynthetic rate, FPAR, albedo, radiation temperature, coverage and CE318 solar spectrophotometer atmospheric parameter data.Measurement content:(1) The radiation temperature data measured by hand-held infrared thermometer are the temperature data of Yingke oasis corn field, huazhaizi desert corn field and huazhaizi desert sample plot 2. The measuring instrument of corn field is the hand-held infrared thermometer of Beijing Normal University, and the sampling methods are canopy vertical observation and strip observation. The sampling method of huazhaizi desert sample plot 2 is canopy diagonal observation. The data includes original data, recorded data and temperature data after blackbody calibration. The original data of this data is in doc format of word. After processing, the data is saved in Excel format.(2) The component temperature is measured by hand-held infrared thermometer. The measured objects are corn and wheat in Yingke oasis, Yingke wheat and huazhaizi desert. When observing maize, the component temperature refers to: ① maize vertical canopy temperature: the radiation temperature of maize leaves under vertical light; ② Bare soil temperature of corn: bare soil temperature of light between corn ridges; ③ Plastic film temperature: plastic film in corn ridge. When observing wheat, the component temperature refers to: ① wheat vertical canopy temperature: vertically observing wheat canopy temp
