This data article presents a high‐resolution map of available water content (AWC) for Senegal, derived from the iSDA Africa dataset and the USDA Rosetta3 model, as well as the method used for its production. The map covers the entire country at a resolution of 30 m and provides a valuable resource for hydrological studies and spatialized crop model simulations in the region where water is a limiting factor for crop production. The dataset is based on existing soil properties data and leverages pedotransfer functions (PTFs) to estimate water retention capabilities from soil properties. This AWC map derived from datasets with enhanced accuracy offers a more precise estimate of soil water retention capacity, which can be instrumental in informing water and agricultural management, policy decisions and investments. The dataset, including intermediate variables, is available in geotiff format at Cirad Dataverse under the DOI 10.18167/DVN1/SGNSII and complies with FAIR data principles, allowing its broad reuse. The code used to produce this dataset is also made available under the DOI 10.5281/zenodo.10078399, so that AWC maps can be produced for any territory covered by the iSDA Africa product.

使用 iSDA Africa 数据集和 USDA Rosetta3 模型绘制塞内加尔可用水含量的高分辨率地图

本数据文章介绍了塞内加尔可用水含量 (AWC) 的高分辨率地图，该地图源自 iSDA Africa 数据集和 USDA Rosetta3 模型及其生成方法。该地图以30 m的分辨率覆盖了整个国家，为水文研究和空间化作物模型模拟提供了宝贵的资源，该地区的水是作物生产的限制因素。该数据集基于现有的土壤特性数据，并利用土壤传递函数 (PTF) 来估计土壤特性的保水能力。这张 AWC 地图源自更高精度的数据集，可以更精确地估计土壤保水能力，这有助于为水和农业管理、政策决策和投资提供信息。该数据集（包括中间变量）可在 DOI 下的 Cirad Dataverse 中以 geotiff 格式获取10.18167/DVN1/SGNSII并符合公平数据原则，允许其广泛重用。用于生成此数据集的代码也可在 DOI 下获取10.5281/泽诺多.10078399，以便可以为 iSDA Africa 产品覆盖的任何地区制作 AWC 地图。
