Metabolism estimates for 356 U.S. rivers (2007-2017)

This data release provides modeled estimates of gross primary productivity, ecosystem respiration, and gas exchange coefficients for 356 streams and rivers across the United States. The release also includes the model input data and alternative input data, model fit and diagnostic information, spatial data for the modeled sites (catchment boundaries and site point locations), and potential predictors of metabolism such as discharge and light availability. The data are organized into these items: Site data - Site identifiers, details, and quality indicators - Table with 1 row per site (tab-delimited file) Spatial data a. Site coordinates - One shapefile of points for all sites combined (.shp, .shx, .dbf, and .prj files) b. Site catchment boundaries - One shapefile of polygons for all sites combined (.shp, .shx, .dbf, and .prj files) Timeseries data - Data on water quality and quantity, collected or computed from outside sources - Tables with one row per time series observation (1 tab-delimited file per site-variable combination, 1 zip file per site) Model inputs - Data formatted for use in estimating metabolism - Tables of prepared time series inputs (1 tab-delimited file per site, in 1 zip file per site) Model configurations - Model specifications used to estimate metabolism - Table with 1 row per model (1 tab-delimited file, compressed into zip file) Model outputs - Complete fits from metabolism estimation models - Text and 4 tables for each model (tab-delimited files, 1 zip file per model) Model diagnostics - Key diagnostics and overall assessments of model performance - Table with 1 row per model (1 tab-delimited file, compressed into zip file) Metabolism estimates and predictors - Daily metabolism estimates and potential predictor variables to support further exploration - Table with 1 row per site-date combination (1 tab-delimited file, compressed into zip file) This work was funded by the USGS Powell Center (Working Group title: "Continental-scale overview of stream primary productivity, its links to water quality, and consequences for aquatic carbon biogeochemistry"). Additional financial support came from the USGS NAWQA program and Office of Water Information. NSF grants DEB-1146283 and EF1442501 partially supported ROH. The USGS Wisconsin Modeling Center provided access to the HTCondor cluster for generating metabolism estimates.
