Model archive and data for water budget components in Minnesota simulated with the Soil-Water-Balance model for past (1981-2022) and future (2040-2059 and 2080-2099) periods

This data release contains a model archive, ancillary data, and outputs for an application of the Soil-Water-Balance (SWB) model code (version 2, Westenbroek and others, 2018) to simulate water budget components at a 1-kilometer resolution for the state of Minnesota. The SWB model was calibrated to streamflow and actual evapotranspiration observations in 71 watersheds for 2000 - 2022.  Two sets of water budget estimates were simulated by the calibrated Minnesota SWB model. First, water budget components for the historical period of 1981 - 2022 were simulated using historical observed PRISM weather data (PRISM Climate Group and Oregon State University, 2022). Second, water budget components for the periods 1995-2014, 2040-2059, and 2080-2099 were estimated using high-resolution (4-kilometer), dynamically downscaled global climate models (GCMs, Liess and others, 2026). The dynamically downscaled daily data sets were generated for every combination of six GCMs for two periods (mid-century, 2040-59 and late century, 2080-99) and three Shared Socioeconomic Pathways (SSP) emissions scenarios (SSP245 [intermediate emissions], SSP370 [high emissions], and SSP585 [very high emissions]).  For each of the six GCMs, a daily dataset was also completed for the historical period of 1995-2014. This model archive has 4 child items. Further details about this application of the SWB model can be found in the related primary publication.
