  "description": "This data release presents truth data and benchmark results describing simulation of hydrologic drought events in the conterminous United States. This data release supports a publication (Simeone and others, 2024) which documents drought benchmarking methods and their application to the results of the National Hydrologic Model Precipitation-Runoff Modeling System v1.0 (NHM-PRMS). Truth data used were observations at U.S. Geological Survey streamgages across the conterminous United States. These data include 4662 U.S. Geological Survey streamgages with a historical period from 1984-2016. The following files are included in this data release: \n1) kappa_long_nhm.csv: Benchmark results for the Cohen's kappa evaluation metrics in long table format. \n2) spear_bias_dist_long_nhm.csv: Benchmark results for the Spearman's, bias, and distributional evaluation metrics in long table format. \n3) ann_eval_long_nhm.csv: Benchmark results for the annual drought evaluation metrics in long table format. \n4) streamflow_percentiles_nhm.zip: A zip file containing individual streamflow percentile data files used in this analysis as truth data. \n5) input_data_nhm.zip: A zip file with input data for individual streamgages used for our data analysis pipeline as truth data. \n6) streamflow_gages_in_study.csv: Metadata information for the 4662 U.S. Geological Survey streamgages contained in the above datasets.",
