2008年5月28日，在临泽草地加密观测区的样方B（盐碱地）、样方D（苜蓿地）和样方E（大麦地）中进行了ASTER的地面同步观测试验，本数据可为机载－星载遥感数据的地表温度及蒸散发反演和验证提供数据。本试验观测内容包含地表辐射温度和浅层土壤水分，样方大小为360m×360m，各样点间距为60m，每个样方总共49个样点。\n
\n地表辐射温度观测：样方B、D和E：温度同步测量时，采用手持式红外温度计呈东西向线状进行连续测量，在数据表中由样点编号标出测量行进路线的起点和终点（起点和终点间距离均为60m），例如D22-23，表示从D样方的22号样点向23号样点前进。样点和样方分布请参见草地加密观测区样方分布图。样方B为等间距采样方案，即从起点开始，每5m进行5次测量；样方D和样方E为非等间距测量，在前进的过程中随机测量。手持式红外温度计定标信息请参见数据目录里面的“手持式热辐射仪定标数据.xls”。\n
\n土壤水分观测：样方B：采用环刀取土经烘干获得重量含水量、体积含水量及土壤容重；针式温度计获得0-5cm平均土壤温度；样方D：采用POGO便携式土壤传感器获得土壤温度、土壤水分、损耗正切、土壤电导率、土壤复介电实部及虚部；针式温度计获得0-5cm平均土壤温度；样方E：采用WET土壤水分速测仪测量获得土壤含水量、电导率、土壤复介电常数实部及土壤温度；并使用针式温度计获得0-5cm平均土壤温度。\n
\n本数据集共包括样方B、样方D和样方E的土壤水分和地表辐射温度一共六个Excel表格。\n样方样带的分布信息请参见元数据“黑河综合遥感联合试验：临泽草地加密观测区样方样带布置”。

The observation contents of this test include surface radiation temperature and shallow soil moisture, and the quadrat size is 360m × 360m, the spacing between various points is 60m, and there are 49 sample points in each quadrat.\n
\nSurface radiation temperature observation: quadrats B, D and E: during simultaneous temperature measurement, the hand-held infrared thermometer is used for continuous measurement in an east-west linear shape. The starting point and end point of the measurement route are marked by the sample point number in the data sheet (the distance between the starting point and the end point is 60m), such as d22-23, which means moving from sample point 22 of quadrat d to sample point 23. For the distribution of sampling points and quadrats, please refer to the quadrat distribution map of grassland intensive observation area. Quadrat B is an equidistant sampling scheme, i.e. 5 measurements every 5m from the starting point; Quadrat D and E are non equidistant measurements, which are measured randomly in the process of advance. For calibration information of hand-held infrared thermometer, please refer to \"calibration data. XLS of hand-held thermal radiometer\" in the data directory.\n
\nSoil moisture observation: quadrat B: the weight water content, volume water content and soil bulk density are obtained by taking soil with a ring knife and drying; Needle thermometer to obtain 0-5cm average soil temperature; Quadrat D: pogo portable soil sensor is used to obtain soil temperature, soil moisture, loss tangent, soil conductivity, real and imaginary parts of soil complex dielectric; Needle thermometer to obtain 0-5cm average soil temperature; Quadrat e: soil moisture content, electrical conductivity, real part of soil complex dielectric constant and soil temperature are measured by wet soil moisture meter; A needle thermometer was used to obtain an average soil temperature of 0-5cm.\n
