NEON Soil Preferential Flow Database

Preferential flow in soil important in supporting water and nutrients transportations. We derivate a preferential flow database using multi-depth soil moisture and precipitation measurements in NEON sites. The database contains water flow velocity for each precipitation event for any given sensor, site characteristics, soil characteristics at each sensor depth etc.

土壤优先流（preferential flow）在支撑水分与养分运移方面发挥着关键作用。本研究基于NEON站点的多深度土壤湿度与降水观测数据，构建了优先流数据库。该数据库涵盖了各传感器对应每场降水事件的水流流速、站点特征以及各传感器埋设深度处的土壤特征等多项信息。
