Data

In cooperation with the West Virginia Division of Transportation, Department of Highways (WVDOH), precipitation and streamflow were measured at four streamgages in West Virginia to compute time of concentration (Tc) and compare it to Tc estimates made using accepted methods. Precipitation and streamflow data were collected during 2017-2020. Storms were identified and classified through...

Three different CMIP6-LOCA2 based climate projection data sets are spatially averaged for the contiguous United States using National Park Service administrative units to provide time series for analysis. The primary data set is the statistically downscaled CMIP6-LOCA2 (Localized Constructed Analogs, v20220519 version, Pierce et al. 2023), which includes temperature and precipitation...

Three different CMIP6-LOCA2 based climate projection data sets are spatially averaged for the contiguous United States using Bureau of Land Management administrative units to provide time series for analysis. The primary data set is the statistically downscaled CMIP6-LOCA2 (Localized Constructed Analogs, v20220519 version, Pierce et al. 2023), which includes temperature and precipitation...

Three different CMIP6-LOCA2 based climate projection data sets are spatially averaged for the contiguous United States counties to provide time series for analysis. The primary data set is the statistically downscaled CMIP6-LOCA2 (Localized Constructed Analogs, v20220519 version, Pierce et al. 2023), which includes temperature and precipitation projections from the Climate Model...

Three different CMIP6-LOCA2 based climate projection data sets are spatially averaged over the Watershed Boundary Dataset (WBD) using HU8 and HU10 hydrologic units for the contiguous United States to provide time series for analysis. The primary data set is the statistically downscaled CMIP6-LOCA2 (Localized Constructed Analogs, v20220519 version, Pierce et al. 2023), which includes...

Data include grass carp position and sampling data from 2022 to 2023. We used grass carp that were implanted with acoustic transmitters. The position data was generated in Fathom Position from receivers that composed several VEMCO Positioning Systems (VPS). We also queried the Great Lakes Acoustic Telemetry Observation Network (GLATOS) to obtain non-VPS position detections from receivers...

This dataset includes simulated streamflow and sediment discharge for major tributaries contributing to Clear Lake, California. Historical hourly streamflow and sediment for each tributary location were outputs from an Hydrological Simulation Program - FORTRAN (HSPF) model. The historical data is available at an hourly time step from October 1980 to March 2024. The future time series...

Samples from the Alaska Placer Concentrate Collection (APCC) were retrieved from the USGS National Geochemical Sample Archives and submitted for mineralogical analysis at the Colorado School of Mines. The APPC contains samples from placer mining operations throughout Alaska. The original collection contained approximately 5,000 samples that were collected by U.S. Geological Survey...

This data release contains a bibliography of U.S. Geological Survey publications on carbon and greenhouse gas research. Publications between 2014 and 2024 were identified using search terms such as: carbon, greenhouse gas, methane, nitrous oxide, emission, sequestration, and primary productivity. Publications were primarily sourced from the USGS Publications Warehouse (https://pubs.usgs...

This dataset includes lab data for stable isotopes of fish tissue, invertebrates, and vegetation collected during daylight hours in the Northern Sacramento-San Joaquin Delta and drainage channels of the Yolo By-Pass, California, USA during summer 2022, 2023, and 2024. This data release includes all animal taxa and isotope values.

This model archive (Fan et al. 2025a) provides all data, code, and model outputs used in the corresponding manuscript (Fan et al. 2025b) to test machine learning (ML) methods for downscaling and multi-scale modeling of stream temperature to combine an ML model and/or input data at coarse spatial resolution with an ML model and/or input data at fine spatial resolution to predict stream...

Datasets includes groundwater well locations and 2015 water-level measurements for 31 wells, 20-foot contours, and water-level change for 31 wells measured in 2009 and 2015 of the Cockfield (upper Claiborne) aquifer. Data also includes groundwater well locations and 2015 water-level measurements for 37 wells, 10-foot contours of the northern Wilcox aquifer, 20-foot contours of the...
