小滦河流域土壤温湿度传感器网络观测数据集（2018-2019）

该数据集包含位于小滦河流域布设29个土壤温湿仪器观测点，观测时间在2018年8月28日-2019年2月28日之间，时间间隔30 min。观测深度为5 cm和10cm共2层。观测点位分布在被动微波像元尺度(如SMAP、SMOS、AMSR2和FY-3)和主动微波卫星像元尺度(如Sentinel-1)内。主微波像元和被动微波像元的观测面积分别为0.1°×0.1° 和 0.25°×0.25°。主动微波像元中有12个位点(称A(主动))，被动微波像元中有17个位点(称P(被动))。

This dataset contains 29 soil temperature and moisture monitoring stations deployed in the Xiaoluanhe River Basin. The observations were conducted between August 28, 2018 and February 28, 2019, with a temporal sampling interval of 30 minutes. Soil measurements are taken at two depths: 5 cm and 10 cm. These monitoring stations are distributed within both passive microwave satellite pixel scales (e.g., SMAP, SMOS, AMSR2, and FY-3) and active microwave satellite pixel scales (e.g., Sentinel-1). The observation areas of active microwave pixels and passive microwave pixels are 0.1°×0.1° and 0.25°×0.25°, respectively. Among these stations, 12 are located within active microwave pixels (designated as Group A (active)), while the remaining 17 are within passive microwave pixels (designated as Group P (passive)).
