%X On June 15, 2008, the ground synchronous observation of imaging spectrometer omis-ii aviation flight was carried out in the intensive observation area of Linze station, mainly measuring soil moisture and surface radiation temperature. 1. Soil moisture observation; Observation target: 0-5cm topsoil. Observation instrument: ring knife (volume 50cm ^ 3). Observation quadrat and sampling times: ly06 and ly07 quadrats (9 observations each) under the sixth and seventh route from east to west. The pretreatment data is soil volume water content. Data storage: Excel.V2. 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 quadrat and sampling times: ly06 quadrat under Route 6 from east to West (49 observation points for each quadrat, 3 repetitions for each observation point during each aircraft transit, a total of 3 crossings, but the transit interval of route 5 and 6 is small, only one observation, marked in the data) and ly07 quadrat under Route 7 (49 observation points for each quadrat, Each time an aircraft crosses the border, each observation point repeats three times (a total of three crossings). 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. See the metadata "Heihe integrated remote sensing joint test: layout of quadrat transects in the densified observation area of Linze station" for the distribution and number of quadrat transects, and see the quadrat transect coordinates.xls of the densified observation
