土壤水分的细微尺度空间变异影响着植物的表现、物种分布和多样性。然而，关于当地土壤水分变化的详细信息很少，特别是在物种丰富的热带森林中。我们在巴拿马巴罗科罗拉多岛(BCI)的50公顷森林动态地块测量了土壤水势和土壤水分，巴罗科罗拉多岛是世界上研究最深入的热带森林之一。我们给出了常规年份和厄尔尼诺干旱期间几个旱季阶段的土壤水势图。此外，我们还提供了允许用户为特定日期创建地图的代码。这些地图可以与其他免费提供的数据集相结合，例如长期植被普查(从种子到成年树木)、关于其他资源的数据(例如光和养分)和遥感数据(例如激光雷达和成像光谱学)。用户可以在当前和未来的气候条件下研究不同学科的问题，如种群和群落生态学、植物生理学和水文学。
Fine scale spatial variation in soil moisture influences plant performance, species distributions and diversity. However, detailed information on local soil moisture variation is scarce, particularly in species-rich tropical forests. We measured soil water potential and soil water content in the 50-ha Forest Dynamics Plot on Barro Colorado Island (BCI), Panama, one of the best-studied tropical forests in the world. We present maps of soil water potential for several dry season stages during a regular year and during an El Niño drought. Additionally, we provide code that allows users to create maps for specific dates. The maps can be combined with other freely available datasets such as long-term vegetation censuses (ranging from seeds to adult trees), data on other resources (e.g. light and nutrients) and remote sensing data (e.g. LiDAR and imaging spectroscopy). Users can study questions in various disciplines such as population and community ecology, plant physiology and hydrology under current and future climate conditions.
