On July 4, 2008, L & K band airborne microwave radiometer aerial remote sensing ground synchronous observation was carried out on the desert microwave flight ground synchronous route in the intensive observation area of Linze station, and soil moisture and surface radiation temperature were observed.\n
\n1. Soil moisture observation; Observation target: 0-5cm topsoil. Observation instrument: ring knife (volume 50cm ^ 3). Observation quadrat and sampling times: Desert microwave synchronous P1 to P6 transects, 17 observation points in each transect, one observation at each observation point, and the observation points have corresponding photos. The pretreatment data is soil volume water content.\n
\n2. Observation of surface radiation temperature. Observation instrument: hand held infrared thermometer (cold and drought Institute 5#, cold and drought Institute 6#, Geography Institute); All instruments have been calibrated (please refer to the calibration data of handheld infrared thermometer. XLS). Observation quadrat and sampling times: Desert microwave synchronous P1 to P6 transects. There are 17 observation points in each transect, each observation point is repeated for 3 times, and the observation points have corresponding photos. 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.\n
