Saxe, S.W., Farmer, W.H., Driscoll, J.M., and Hogue, T., 2020, Collection of Hydrologic Models, Reanalysis Datasets, and Remote Sensing Products Aggregated by Ecoregion over the CONUS from 1900 to 2018: U.S. Geological Survey data release,


This is accompanying data produced for the study "Implications of Model Selection: Inter-Comparison of Publicly-Available, CONUS-Extent Hydrologic Component Estimates". These datasets were converted from their primary structures (rasters and shapefiles) to EPA Ecoregions Level I. Conversion was performed by averaging timestep layers via mean area weight to produce a single vector of monthly values for each ecoregion, for each of the following hydrologic cycle components: precipitation (P), actual evapotranspiration (AET), runoff (R), snow water equivalent (SWE), rootzone soil moisture in equivalent water depth (RZSME), and rootzone soil moisture in volumetric water content (RZSMV).

Data were obtained in order to quantitatively compare estimates of the hydrologic cycle across the conterminous United States. Estimates used in this study were generated by government and university research organizations by applying hydrologic modeling, remote sensing observations, and reanalysis algorithms.
