A novel benchmark dataset of daily groundwater recharge

A newly developed benchmark dataset of groundwater recharge per unit specific yield (RpSy) at daily temporal resolution is presented. The data has been obtained through the application of the Water table Fluctuation (WTF) method at groundwater wells within the continental US. To ensure high-fidelity estimates, only wells that meet a set of stringent criteria have been considered. The resulting product is a continuous daily RpSy time series data for 81 groundwater wells. The data files are provided in the .csv format and consist of two columns for each observation well. The first column lists the local time while the second column provides the RpSy time series in meters per day. Additionally, a file containing site information for all the selected wells is included. It contains four columns that detail the USGS ID of the groundwater well, its latitude (Lat), longitude (Long), and screen depth (depth) in meters. The data file can be accessed in most text editors and spreadsheets.
