Soil Water Infiltration Global (SWIG) Database

In this database we present and analyze a global database of soil infiltration measurements, Soil Water Infiltration Global (SWIG) database, for the first time. In total, 5023 infiltration curves were collected across all continents. These data were either provided and quality checked by the scientists who performed the experiments or they were digitized from published articles. Data from 54 different countries were included in the database with major contributions from Iran, China, and USA. In addition to its global spatial coverage, the collected infiltration curves cover a time span of research from 1976 to late 2017. […]

本数据库首次呈现并分析了全球土壤入渗测量数据集——土壤水入渗全球数据库（SWIG），其中收录了涵盖所有大陆的5023条入渗曲线。这些数据要么由进行实验的科学家提供并经过质量检验，要么从已发表的论文中数字化而来。数据库中包含了来自54个不同国家的数据，其中伊朗、中国和美国贡献尤为显著。除了其全球空间覆盖范围外，所收集的入渗曲线还涵盖了1976年至2017年底的研究时间跨度。
