%X On May 28, 2008, the aster satellite ground synchronous observation test was carried out in the encrypted observation area of Linze station. The observation contents include soil moisture, surface radiation temperature, surface feature spectrum and BRDF. ASTER data not obtained. 1. Soil moisture observation; Observation target: 0-5cm topsoil. Observation instrument: ring knife (volume 50cm ^ 3), ml2x soil moisture rapid tester. Observation quadrats and observation times: Desert East-West sample belt (including 40 sub quadrats, each sub quadrat corner point is sampled once), desert north-south sample belt (including 9 sub quadrats, each sub quadrat corner point is sampled once), wulidun farmland sample is sampled at the midpoint of 9 small quadrats, sample No. 5 in the center is encrypted, and 4 corner points are also sampled (each measuring point is sampled once with a ring knife), Ml2x soil moisture meter (1 observation). The pretreatment data is soil volume water content. Data storage: Excel. 2. Surface radiation temperature observation; Observation instrument: hand held infrared thermometer (cold and drought Institute 5#, cold and drought Institute 6#), and the instruments have been calibrated (please refer to the calibration data of hand-held infrared thermometer. XLS). Observation quadrats and sampling times: Desert East-West sample zone (including 40 sub quadrats, 14-30 observations in each sub quadrat), desert north-south sample zone (including 9 sub quadrats, 12-30 observations in each sub quadrat). Preprocessing data according to the thermal infrared calibration data (the standard source is blackbody), the measured temperature of each instrument is linearly fitted with the corresponding blackbody temperature to obtain the fitting equation, and then the above fitted equation is used to calibrate the observed original observation data. Data storage: Excel. 3. Ground feature spectrum; Observation instrument: ASD spectrometer of Beijing Normal University, 350-2
