These netCDF output files from the Soil-Water-Balance Model contain daily calculations for the Shellmound inset area within the Mississippi Embayment Regional Aquifer System model domain of irrigation, net infiltration (recharge), runoff, soil moisture storage, and actual evapotranspiration amounts for the years 2000 to 2018 and gross precipitation as read from DayMet and processed through the USGS Soil-Water-Balance Model v.2.0 (Westenbroek and others, 2018). Input files used in the SWB run included agricultural land use as estimated by Brown and Pervez (2014) and provided by the USDA National Agricultural Statitical Service (Boryan and others, 2011), and soil properties derived from NRCS gSSURGO and STATSGO data (Wieczorek, 2014). Calculations were driven by DayMet version 3 daily precipitation and air temperatures (Thornton and others, 2018). Further details about the generation and application of the data can be found in Open File Report 2021-1008 (https://doi.org/10.3133/ofr20211008). These data are extracted from the model output contained in the companion model archive data release: https://doi.org/10.5066/P98PBR8O.
