%X On July 11, 2008, the airborne wide-angle infrared dual-mode line / area array scanner (widas) and ENVISAT ASAR satellite synchronous ground observation test were carried out in the encrypted observation area of Linze station. The observation contents include soil moisture, surface radiation temperature, ground object spectrum, BRDF, LAI-2000 measurement Lai, fish eye camera measurement Lai, manual measurement Lai, etc. 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). ENVISAT ASAR data is AP mode, VV / VH polarization combination mode, and the transit time is about 11:26bjt.1. Soil moisture observation; Observation target: 0-5cm topsoil. Observation instrument: ring knife (volume 50cm ^ 3), ml2x soil moisture rapid tester. Observation quadrats and sampling times: Desert East-West sample zone (including 40 sub quadrats, and each sub quadrat's corner point ring knife is sampled once), desert north-south sample zone (including 9 sub quadrats, and each sub quadrat's corner point ring knife is sampled once), ly06 and ly07 quadrats under the East-West flight route (9 observations each), wulidun farmland quadrat (each observation point ring knife is sampled once, Ml2x soil moisture meter (3 repetitions). 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#, Geography Institute); All instruments have been calibrated (please refer to the calibration data of handheld infrared thermometer. XLS). Observation quadrats and sampling times: ly06 and ly07 quadrats (49 observation points for each quadrat, 3 repetitions for each observation point) and wulidun farmland q
