Selected evapotranspiration data were collected between 7/8/2010 and 11/2/2012 at two eddy covariance sites and from 6/8/2011 to 11/2/2012 at two additional eddy covariance sites in Kobeh Valley, central Nevada. The data presented in this data release includes 30-minute and daily evapotranspiration and associated energy-balance fluxes, precipitation, soil water content, air and soil temperature, wind speed and direction, humidity, and photosynthetically active radiation data. Data collection and processing methods follow those described in Berger and others (2016). Berger, D.L., Mayers, C.J., Garcia, C.A., Buto, S.G., and Huntington, J.M., 2016, Budgets and chemical characterization of groundwater for the Diamond Valley flow system, central Nevada, 2011–12: U.S. Geological Survey Scientific Investigations Report 2016–5055, 83 p., http://dx.doi.org/10.3133/sir20165055 .

This USGS data release represents supplemental tabular data for an annual groundwater discharge by evapotranspiration (ET) from areas of spring-fed riparian vegetation, Stump Spring and Hiko Springs, Clark County, Nevada, 2016-18. The raw ET dataset contained multiple data gaps that were simulated and gap-filled with the water-level model utility in SeriesSEE, a USGS developed Microsoft Excel® addin. Continuous time-series data, including net radiation, sensible-heat flux, latent-heat flux, and ground-heat flux, from before and after the data gap(s) were used to simulate turbulent fluxes with multivariate regressions and the gramma transform, used for latent heat gaps after precipitation events. ET data were gap filled using methods outlined in A process to estimate net infiltration using a site-scale water-budget approach, Rainier Mesa, Nevada National Security Site, Nevada, 2002–05. Data used to simulate gap periods for Stump Spring and Hiko Springs were acquired from USGS ET stations 364555117412401 and 355846116160401, respectively. This release consists of the following: (1) inventory of latent-heat flux, sensible-heat flux gap-filled periods, and model goodness-of-fit, Stump Springs, Clark County, NV, 2016, (2) inventory of net radiation, latent-heat flux, sensible-heat flux, ground-heat flux gap-filled periods, and model goodness-of-fit, Hiko Springs, Clark County, NV, 2017-18, (3) gap-filled latent-heat flux and sensible-heat flux data, Stump Spring evapotranspiration station, Clark County, NV, 2016, and (4) gap-filled net radiation, latent-heat flux, sensible-heat flux, and ground-heat flux, Hiko Springs evapotranspiration station, Clark County, NV, 2017-18.

,Detailed hydrometeorological data from the mountain rain-to-snow transition zone are present for water years 2004 through 2014. The Johnston Draw watershed (1.8 km2), ranging from 1497 – 1869 m in elevation, is a sub-watershed of the Reynolds Creek Experimental Watershed (RCEW) in southwestern Idaho. The dataset includes continuous hourly hydrometeorological variables across a 372 m elevation gradient, on north- and south-facing slopes, including air temperature, relative humidity and snow depth from 11 sites in the watershed. Hourly measurements of solar radiation, precipitation, wind speed and direction, and soil moisture and temperature are available at selected stations. The dataset includes hourly stream discharge measured at the watershed outlet. These data provide the scientific community with a unique dataset useful for forcing and validating models in interdisciplinary studies and will allow for better representation and understanding of the complex processes that occur in the rain-to-snow transition zone.,This version of the data set fixes errors in all data files and supersedes the earlier datasets https://doi.org/10.15482/USDA.ADC/1258769 and https://doi.org/10.15482/USDA.ADC/1245163.,See the file inventory included with this dataset for more information on individual data files.,For more information about this dataset contact: Clarissa L.

This U.S. Geological Survey data release presents monthly evaporation estimates from Lake Mead, Nevada and Arizona. Data are updated approximately annually. The spreadsheet includes five worksheets: (1) Read_Me worksheet contains information relevant to understanding the data contained in the rest of the worksheets. (2) Monthly_EC_Met worksheet includes data measured at a land-based station (USGS site identification number 360500114465601) using primarily eddy covariance measurement methods: uncorrected evaporation, latent- and sensible-heat fluxes, net radiation, air temperature, wind speed, and relative humidity. Values are monthly averages computed by averaging daily values except as noted. Monthly values are marked as estimated when a significant portion of daily values are estimated. (3) Monthly_Energy-Budget_Data worksheet includes computed data used to correct measured evaporation for energy balance. Computed data include monthly values for change in stored heat, net advection, turbulent flux, available energy, energy balance ratio, energy balance closure, and Bowen ratio. Change in stored heat was calculated based on methods in Earp and Moreo (2021). Net advection was calculated based on data estimated by the Bureau of Reclamation 24-Month Study (2022). Values are monthly averages or computed from monthly averages. (4) Annual_Energy_Balance worksheet includes annual averages of the Monthly_Energy_Balance data and the annual average values for energy-balance corrected sensible and latent heat fluxes. Values are annual averages or computed from annual averages. (5) Monthly_Evaporation_Estimates worksheet includes measured evaporation, corrected (most probable) evaporation, and energy balance ratio (EBR) adjusted evaporation, in feet. Values are monthly averages or computed from monthly averages. Data were processed according to methods described in Moreo and Swancar (2013) and Earp and Moreo (2021).

This data set contains precipitation stations and precipitation-zone boundaries of west-central Nevada.

This data set contains precipitation stations and precipitation-zone boundaries of west-central Nevada.

Meteorological data was collected from two locations in the Agashashok River Watershed, one high in the drainage located on tundra (67.5440 N, 161.6828 W) and a second on a rocky knoll near the watershed mouth (67.2821 N, 162.5841 W). The data contain information on air temperatures, rainfall, barometric pressure, relative humidity, incoming and outgoing radiation, and wind speed and direction. Data collection was discontinued due to equipment failure and substantial demolition of one station by a bear.

This dataset includes air temperatures from 50 data loggers that were installed in tandem with stream temperature data loggers, as well as five ridgetop data loggers, throughout the Willow/Rock/Frazer watersheds of northern Nevada between July 31 and August 15, 2015. Fifty-one data loggers were recovered and downloaded in late July 2016.
