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 main variable of ground synchronous observation is surface temperature

In the intensive observation area of Linze grassland, the surface temperature of quadrat a (reed land), quadrat B (saline alkali land), quadrat C (saline alkali land), quadrat D (alfalfa land) and quadrat e (barley land) are measured by hand-held infrared thermometer. During the measurement, continuous measurement shall be carried out along the northeast direction.\n
