Wieczorek, M.E., 2014, Area- and Depth-Weighted Averages of Selected SSURGO Variables for the Conterminous United States and District of Columbia: U.S. Geological Survey data release, https://doi.org/10.5066/P92JJ6UJ.

Summary

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This digital data release consists of seven national data files of area- and depth-weighted averages of select soil attributes for every available county in the conterminous United States and the District of Columbia as of March 2014. The files are derived from Natural Resources Conservations Service’s (NRCS) Soil Survey Geographic database (SSURGO). The data files can be linked to the raster datasets of soil mapping unit identifiers (MUKEY) available [...]

Purpose

The data were derived for use in studies requiring estimates of soil characteristics. The georeferenced soil characteristics were intended to be averaged over large areas, such as over a river basin, and used for (1) watershed simulation models that require spatially lumped estimates of soil hydraulic parameters, and (2) as explanatory variables in regional and national water-quality assessment studies.
