Landscape Characterization and Representativeness Analysis for Understanding Sampling Network CoverageDamian Maddalena, Forrest Hoffman, Jitendra Kumar & William Hargrove
Sampling networks rarely conform to spatial and temporal ideals, often comprised of network sampling points which are unevenly distributed and located in less than ideal locations due to access constraints, budget limitations, or political conflict. Quantifying the global, regional, and temporal representativeness of these networks by quantifying the coverage of network infrastructure highlights the capabilities and limitations of the data collected, facilitates upscaling and downscaling for modeling purposes, and improves the planning efforts for future...
California State University Long Beach evaluated hydraulic connectivity among geothermal wells using Periodic Hydraulic Testing (PHT) and Distributed Acoustic Sensing (DAS). The principal was to create a pressure signal in one well and observe the responding pressure signals in one or more observation wells to assess the permeability and storage of the fracture network that connects the two wells. DAS measured strain at mHz frequency in monitoring wells in response to PHT.
Field measurements of mean flow and turbulence parameters at the Kvichak river prior to and after the deployment of ORPC's RivGen hydrokinetic turbine. Data description and turbine wake analysis are presented in the attached manuscript "Wake measurements from a hydrokinetic river turbine" by Guerra and Thomson (recently submitted to Renewable Energy). There are three data sets: NoTurbine (prior to deployment), Not_Operational_Turbine (turbine underwater, but not operational), and Operational_Turbine. The data has been quality controlled and...
LTE Device-to-Device Out-of-Coverage Communication with Frequency Hopping Resource Scheduling Performance Metrics Evaluation DataFernando Cintron
This dataset represents the results from conducted simulations to evaluate the performance of Device-to-Device (D2D) communications in LTE when the User Equipment (UEs) are operating in UE-scheduled mode (Mode 2) with frequency hopping enabled. Different scenarios were simulated and communication performance was evaluated for each frequency hopping scheme defined in the LTE standard. The communication performance metrics include the successful transmission- reception ratio of transport blocks (TBs) at the physical layer, and the probability mass...

The ARM CMBE-ATM [Xie, McCoy, Klein et al.] data file contains a best estimate of several selected atmospheric quantities from ACRF observations and NWP analysis data.
Aluminum is an optimized GPU-aware communication library. It provides a generic Interface to high-performance allreduce algorithms, with support for additional collective operations in progress. Blocking and non-blocking algorithms and GPU-aware algorithms are supported. Aluminum contains custom Implementations and Interfaces to existing optimized communication libraries, exposed through a generic API.
The information given in this file represents GHG emissions and corresponding emission rates for California flash and dry steam geothermal power plants. This stage of the life cycle is the fuel use component of the fuel cycle and arises during plant operation. Despite that no fossil fuels are being consumed during operation of these plants, GHG emissions nevertheless arise from GHGs present in the geofluids and dry steam that get released to the atmosphere upon...
The primary purpose of WFIP2 Model Development Team is to improve existing numerical weather prediction models in a manner that leads to improved wind forecasts in regions of complex terrain. Improvements in the models will come through better understanding of the physics associated with the wind flow in and around the wind plant across a range of temporal and spatial scales, which will be gained through WFIP2’s observational field study and analysis.

CO2 and CH4 Surface Flux, Soil Profile Concentrations, and Stable Isotope Composition, Barrow, Alaska, 2012-2013J. Curtis, L. Vaughn, M. Torn, M. Conrad, O. Chafe & M. Bill
In August-October 2012 and June-October 2013, co-located measurements were made of surface CH4 and CO2 flux, soil pore space concentrations and stable isotope compositions of CH4 and CO2, and subsurface temperature and soil moisture. Measurements were made in intensive study site 1 areas A, B, and C, and from the site 0 and AB transects, from high-centered, flat-centered, and low-centered polygons, from the center, edge, and trough of each polygon.
A collection of the MAVEN Langmuir Probe and Waves (LPW) spacecraft potential based on all 4 sub-cycles and from both booms merged to one time series. Note that data values of '-nan' can be treated as equivalent to 'nan'.
This data set reports selected ambient environmental monitoring data (public) from the S1 bog for the period June 2010 through 2016. Measurements of the environmental conditions at these stations will serve as a pre-treatment baseline for experimental treatments and provide driver data for future modeling activities.

The National Hydropower Plant Dataset, Version 1, Update FY18Q2, includes geospatial point-level locations and key characteristics of existing hydropower plants in the United States that are currently online. These data are a subset extracted from NHAAP’s Existing Hydropower Assets (EHA) dataset, which is a cornerstone of NHAAP’s EHA effort that has supported multiple U.S. hydropower R&D research initiatives related to market acceleration, environmental impact reduction, technology-to-market activities, and climate change impact assessment.
This data set reports stream temperature, specific conductance, pH, dissolved oxygen percent saturation, dissolved oxygen concentration, and turbidity for East Fork Poplar Creek at a location approximately 16.2 kilometers upstream from the mouth of the creek.
This public data set contains openly-documented, machine readable digital research data corresponding to figures published in D.J. Schlossberg et al., 'Non-Inductively Driven Tokamak Plasmas at Near-Unity Toroidal Beta,' Phys. Rev. Lett. 119, 035001 (2017).
The ProTECT study will determine if intravenous (IV) progesterone (started within 4 hours of injury and given for a total of 96 hours), is more effective than placebo for treating victims of moderate to severe acute traumatic brain injury.
