NEON Stream Discharge (RELEASE-2026) NSE and Regression Dataset

R script used to analyze data and generate the table and figure published in the manuscript 'Evaluation of streamflow estimates generated at aquatic sites across the National Ecological Observatory Network, Water Years 2022-2024' by Harrison et al. (submitted for publication in 2026 to Limnology and Oceanography Letters). First, field and modeled discharge (15-min resolution) are downloaded from the NEON Data Portal. Each field discharge value is mapped to the nearest modeled discharge timestamp. Plots are generated for each site showing the linear fit of field vs. modeled discharge, then stacked into a single plot for output. Finally, an output table is generated that contains the following summary statistics for each site: Nash-Sutcliffe Efficiency (NSE), slope of linear equation, coefficient of determination (R^2) of linear equation, the percent of the period of record that contains NULL modeled discharge, the channel slope of the site, and the watershed area of the site. This material is based in part upon work supported by the National Ecological Observatory Network (NEON), a program sponsored by the U.S. National Science Foundation (NSF) and operated under cooperative agreement by Battelle.
