Supplementary Data for Remote soil moisture measurement from drone-borne reflectance spectroscopy: Applications to hydroperiod measurement in desert playas

This supporting dataset includes: • Ground-based reflectance measurements for the two plume-crossing transects (AHT3 and AHT4). Data show reflectance by wavelength at each scan position. • Reduced data records (RDR) showing GPS position data for the drone and the associated reflectance measurement, by wavelength, averaged over 1 second intervals for the three mapping sorties, AHS4, 5, and 7. • The sample datasheet showing ground-based and lab-base measurements of the sampling transects.本配套数据集包含以下内容： • 两次穿越羽流的采样航迹（AHT3与AHT4）的地面反射率测量数据，数据展示了各扫描位置下不同波长的反射率数值。 • 约简数据记录（Reduced Data Records, RDR），包含无人机GPS位置数据与关联的对应波长反射率测量结果；针对AHS4、AHS5与AHS7三次测绘架次，所有数据均以1秒为间隔进行平均处理。 • 样本数据表，涵盖采样航迹的地面与实验室测量数据。
