The hydrologic model was recalibrated using the R script \u2018annotated_R_script_for_model_recalibration.R\u2019 and the input dataset \u2018Daily_values_for_climate_stage_and_model_terms.csv\u2019 in this data release to produce recalibrated values for the four calibrated parameters in the model: KBR, KPR, KBG, and PG (see the \u2018Entity and Attribute\u2019 section of this metadata document; for additional information see table 9 in Wolfe and others, 2004). The data file \u2018model_recalibration_results.csv\u2019 contains the results from the recalibration process. Each row in the dataset represents a different model, where each model is defined by a unique combination of values for KBR, KPR, KBG, and PG. All possible combinations of KBR (15 parameter values), KPR (13 parameter values), KBG (20 parameter values), and PG (21 parameter values) were run as separate models, to yield a total of 81,900 models (i.e., 81,900 rows in this dataset). Each model produced a time series of modeled pond stage which was compared to observed pond stage on a daily time step across 22 water years to calculate four model performance statistics: (1) root mean-squared error (RMSE), (2) Nash-Sutcliffe Efficiency (NSE), (3) the 25th percentile of NSE values across water years (NSE_p25), and (4) hydroperiod discrepancy (HPD); see the \u2018Entity and Attribute\u2019 section of this metadata document for additional information about model performance metrics.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P96F7JHP", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.5ebc414a82ce25b513652f35.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5ebc414a82ce25b513652f35", "keyword": ["Arnold Engineering Development Complex", "Sinking Pond", "Tennessee", "USGS:5ebc414a82ce25b513652f35", "environment", "hydrology", "inlandWaters", "wetland ecosystems"], "modified": "2021-01-20T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-86.079791164, 35.397754135, -86.049271064, 35.424247954", "theme": ["geospatial"], "title": "Model recalibration results including recalibrated parameters and model performance statistics"}
