\n（ 1) Fixed self recording point thermometer: its field of view angle is about 10 °, and the sampling time interval is 1s (except May 20, 2008). A total of 8 instruments, including 6 in Beijing Normal University, with a specific emissivity of 0.95; There are 2 sets of Remote Sensing Application Institute of Chinese Academy of Sciences, and the specific emissivity of the instrument is 1.0.\n
\nThe multi temporal continuous radiation temperature of each sample plot in the dense observation area of Yingke oasis and huazhaizi desert was measured. The sample plots include Yingke oasis corn plot, Yingke wheat plot, huazhaizi desert corn plot, huazhaizi desert sample plot 1, huazhaizi desert sample plot 2 and three dense sample plots (huazhaizi desert sample plot 3, barley sample plot next to the resort and corn plot next to the resort). Among them, the observation objects in Yingke oasis are mostly corn canopy, bare soil between corn ridges and wheat canopy, and the observation objects in Yingke wheat sample plot are wheat canopy; The observation object of huazhaizi desert corn field is corn canopy; The observation objects of huazhaizi desert sample plot 1 and huazhaizi desert sample plot 2 are vegetation (red sand) and desert bare soil. The erection height of the instrument is related to the ground features, which can be queried from the data file. Vertical observation is adopted. The instrument is also used for flight calibration of thermal infrared camera.\n
\nThis data is synchronized with the flight of airborne data organic infrared wide-angle dual-mode imager widas (wide angle infrared dual-mode line / area array scanner) and imaging spectrometer omis-ii; Spaceborne data include TM, aster, MODIS, hyperspectral Hyperion and Chris sensors. The daily variation of radiation temperature was also measured.\n

\n（ 2) Hand held infrared thermometer: the field of view angle is 1 °, and the temperature sensitivity is 0.1 ° C. The measured sample plots include Yingke oasis corn plot, Yingke wheat plot, huazhaizi desert corn plot, huazhaizi desert sample plot 1, huazhaizi desert sample plot 2, and resort corn sample plot. Each sampling can obtain the maximum, minimum and average radiation temperature in the sampling time period. Among them, Yingke oasis corn field, Yingke wheat field and huazhaizi desert corn field are row sowing crops. The sampling methods are vertical ridge and along ridge strip measurement. During multi angle flight synchronization, the temperature of four components is also measured; Huazhaizi desert sample 1 and huazhaizi desert sample 2 were measured along the diagonal strip, and the resort corn field was measured as the sampling point. The specific emissivity of most instruments is 1 (see the data file for details). The measurement height in strip mode is about 1m and measured vertically downward.\n
