Abstract

<p>We introduce here SOIL-WATERGRIDS, a new dataset of dynamic changes in soil moisture and depth of water table over 45 years from 1970 to 2014 globally resolved at 0.25 x 0.25 degree resolution (about 30 x 30 km at the equator) along a 56 m deep soil profile. SOIL-WATERGRIDS estimates were obtained using the BRTSim model instructed with globally gridded soil physical and hydraulic properties, land cover and use characteristics, and hydrometeorological variables to account for precipitation, ecosystem-specific evapotranspiration, snowmelt, surface runoff, and irrigation. We validate our estimates against independent observations and re-analyses of the soil moisture, water table depth, wetland occurrence, and runoff. SOIL-WATERGRIDS brings into a single product the monthly mean water saturation at three depths in the root zone and the depth of the highest and lowest water tables throughout the reference period, their long-term monthly averages, and data quality. SOIL-WATERGRIDS can therefore be used to analyse trends in water availability for agricultural abstraction, assess the water balance under historical weather patterns, and identify water stress in sensitive managed and unmanaged ecosystems.</p><table> <tr><td>Measurement(s)</td><td>volumetric water content • water table depth</td></tr><tr><td>Technology Type(s)</td><td>computational modeling technique</td</tr><tr><td>Factor Type(s)</td><td>hydrometeorology • soil properties • land use</td></tr><tr><td>Sample Characteristic - Environment</td><td>soil</td></tr></table> <p>Machine-accessible metadata file describing the reported data: <a href="https://doi.org/10.6084/m9.figshare.15982578"> https://doi.org/10.6084/m9.figshare.15982578</p>
