WATER: Dataset of ground truth measurements synchronizing with airborne WiDAS mission in the Linze grassland foci experimental area on May 30, 2008

The dataset of ground truth measurements synchronizing with airborne WiDAS mission was obtained in the Linze grassland foci experimental area on May 30, 2008. WiDAS, composed of four CCD cameras, one mid-infrared thermal imager (AGEMA 550), and one infrared thermal imager (S60), can acquire CCD, MIR and TIR band data. The simultaneous ground data included the land surface temperature measured by the hand-held infrared thermometer in the reed plot A, the saline plots B and C, the alfalfa plot D and the barley plot E, the maximum of which were 120m×120m and the minimum were 30m×30m, and soil gravimetric moisture, volumetric moisture, and soil bulk density after drying measured by the cutting ring and the mean soil temperature from 0-5cm measured by the probe thermometer in plot 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 measured by the POGO soil sensor, and the mean soil temperature from 0-5cm measured by the probe thermometer in plot D and E. See WATER: Dataset of setting of the sampling plots and stripes in the foci experimental area of Linze station for more information.

本数据集于2008年5月30日在临泽草地焦点实验区采集，其包含与空中WiDAS任务同步的地面真实测量数据。WiDAS系统由四台CCD相机、一台中红外热成像仪（AGEMA 550）以及一台红外热成像仪（S60）组成，能够采集CCD、MIR和TIR波段的数据。同时采集的地面数据包括在芦苇地A、盐碱地B和C、苜蓿地D和大麦地E中，由手持式红外温度计测量的地表温度，测量范围最大为120m×120m，最小为30m×30m，以及通过环刀测定的土壤重力水含量、体积水含量和烘干后的土壤容重；在A、B和C地块中，由探头温度计测定的0-5cm土壤平均温度；由POGO土壤传感器测定的土壤温度、土壤湿度、损耗角正切、土壤电导率以及土壤复介电常数实部和虚部，以及D和E地块中由探头温度计测定的0-5cm土壤平均温度。欲了解更多关于采样地块和条带设置的信息，请参阅WATER：临泽站焦点实验区采样地块和条带设置数据集。
