WATER: Dataset of ground truth measurement synchronizing with ALOS PALSAR in the Linze grassland foci experimental area on June 10, 2008

The dataset of ground truth measurement synchronizing with ALOS PALSAR was obtained in the Linze grassland foci experimental area on Jun. 10, 2008. The data were in FBS mode and HH/HV polarization combinations, and the overpass time was approximately at 23:39 BJT. Observations were carried out in plots A, B, C, D and E, which were divided into 6×6 subsites, with each one spanning a 120×120 m2 plot. Soil gravimetric moisture, volumetric moisture, and soil bulk density after drying by the cutting ring and the mean soil temperature from 0-5cm by the probe thermometer were measured in A, B and C; the soil temperature, soil moisture, the loss tangent, soil conductivity, the real part and the imaginary part of soil complex permittivity by the POGO soil sensor, and the mean soil temperature from 0-5cm by the probe thermometer in D and E. Data were archived in Excel file. See WATER: Dataset of setting of the sampling plots and stripes in the foci experimental area of Linze station for more information.

本数据集收录了与 ALOS PALSAR 卫星同步获取的地面真值测量数据，该数据采集于 2008 年 6 月 10 日于林泽草原焦点实验区。数据采集模式为全向散射模式（FBS），极化组合为 HH/HV，过境时间约为北京时间 23:39。观测分别在 A、B、C、D 和 E 五个地块进行，每个地块被划分为 6×6 个子区域，每个子区域覆盖 120×120 平方米的区域。在 A、B 和 C 地块，测量了土壤重力水含量、体积水含量以及经切割环干燥后的土壤容重，以及使用探头温度计测得的 0-5cm 土壤平均温度；在 D 和 E 地块，则使用了 POGO 土壤传感器测量了土壤温度、土壤湿度、损耗正切、土壤电导率、土壤复介电常数的实部和虚部，以及使用探头温度计测得的 0-5cm 土壤平均温度。数据以 Excel 文件格式存档。欲了解更多关于林泽站焦点实验区采样地块和条纹设置的信息，请参阅 WATER 数据集。
