These data are collected by a Streamline XR Doppler Lidar operated by Lawrence Livermore National Laboratory and deployed at the Tree Tops site (1.5 km South-West of MLBS site).
These data are collected by a Streamline XR Doppler Lidar operated by the University of Virginia and deployed at the MLBS site.
This dataset consists of CACO Site netCDF L1 data files containing level 1 (L1) data from the ceilometer.
The present weather detector data provide NWS weather type and codes and visibility metrics. These data would be helpful to easily detect fog over the barge.
This dataset contains raw data from the WFIP3 RHOD site supplementary meteorological sensors: T/RH and barometer; 1-sec average. The supplementary meteorological suite was added to PNNL Surface Flux Station to provide independent measurements of air temperature, relative humidity, and atmospheric pressure.
This dataset contains standardized data from DOE Buoy 140 deployed during WFIP3. *.csv10m.zip files have been converted to netCDF.
This dataset contains standardized data from the WFIP3 Wind Profiler located at the Rhode Island WFIP3 site.
This dataset contains standardized data from the WFIP3 Wind Profiler with Radio Acoustic Sounding System (RASS).
This dataset contains standardized data from the PNNL scanning Doppler lidar (S/N 184), consisting of range- and time-resolved measurements of radial velocity, attenuated backscatter, intensity, and spectral width. We note that the beam azimuth angles are NOT referenced to true north.
These are the standardized buoy data collected during the WFIP3 project period, initially deployed near the Martha's Vineyard region for validation and later deployed at the WFIP3 location. The NetCDF files contain the data for most of the *.csv files for a given day.
This dataset contains formatted lidar data from ground-based NLR Halo XR+235.
This dataset contains plant-level wind power production data from ERCOT, recorded at 15-minute intervals. The source of this data is ERCOT's 60-Day SCED Disclosure Report (product number NP3-965-ER), with timestamps provided in UTC.
This dataset contains standardized data from the WFIP3 NANT site UTD Halo XR Lidar.
The dataset spans November 2018 to May 2020 and includes time-series measurements corresponding to supply and return temperatures of air and water, air, hot water and cold water flow rates, energy and power consumption, set-points etc. as a single CSV file. In addition to the measurements, a metadata .json file, and a .ttl file to visualize the data as per BRICK schema are also included.
We present Event Horizon Telescope (EHT) 1.3 mm measurements of the radio source located at the position of the supermassive black hole Sagittarius A* (Sgr A*), collected during the 2017 April 5–11 campaign. The observations were carried out with eight facilities at six locations across the globe. Novel calibration methods are employed to account for Sgr A*'s flux variability. The majority of the 1.3 mm emission arises from horizon scales, where intrinsic structural source variability is detected on timescales of minutes to hours. The effects of interstellar scattering on the image and its variability are found to be subdominant to intrinsic source structure. The calibrated visibility amplitudes, particularly the locations of the visibility minima, are broadly consistent with a blurred ring with a diameter of ∼50 μas, as determined in later works in this series. Contemporaneous multiwavelength monitoring of Sgr A* was performed at 22, 43, and 86 GHz and at near-infrared and X-ray wavelengths. Several X-ray flares from Sgr A* are detected by Chandra, one at low significance jointly with Swift on 2017 April 7 and the other at higher significance jointly with NuSTAR on 2017 April 11. The brighter April 11 flare is not observed simultaneously by the EHT but is followed by a significant increase in millimeter flux variability immediately after the X-ray outburst, indicating a likely connection in the emission physics near the event horizon. We compare Sgr A*’s broadband flux during the EHT campaign to its historical spectral energy distribution and find that both the quiescent emission and flare emission are consistent with its long-term behavior.
This dataset contains radar moments corrected for clutter, noise, aliasing, and attenuation from the X-band ARM Scanning Precipitation Radar 2 (XSAPR-2).
