A NASA-curated grouping of test cases for collaborative turbulence model validation. The dataset focuses on more recent compressible-flow scenarios, as indicated by the description. It was last updated on March 13, 2026.
NASA HEASARC provides a redshift and photometric catalog for X-ray sources detected in the Chandra Deep Field-North (CDF-N). The table extends previous redshift work with photometric redshifts and includes updated optical and infrared photometric data. It was created in January 2009 based on electronic data from the referenced 2008 paper.
Nomiki Koutsoumpari published a dataset on figshare in May 2026. It contains subject-level summary metrics for simulated thermal and acoustic exposure. The data reports peak temperature, peak pressure, intensity, and a transcranial mechanical index for stimulation targets in the brain.
ARC is designed to produce 400MW of net electricity. This dataset contains magnetohydrodynamic (MHD) stability analysis for the ARC fusion reactor scenario, authored by N. Leuthold et al. from the Plasma Science and Fusion Center, with metadata last updated on 2026-05-08.
STEREO-A PLASTIC provides 1-hour averages of helium ion phase space densities across 51 normalized velocity ranges relative to solar wind speed. The data set includes proton plasma moments and is delivered to the public domain on a regular basis by NASA. Efforts are made to include the latest calibration, but revisions are expected.
Plasma N-glycan profiles from mice reveal time-of-day-dependent changes influenced by a high-fat diet and the SGLT2 inhibitor dapagliflozin. The dataset contains quantitative glycomic measurements from a controlled experiment, with drug administration timed in the morning or at night. Yurika Ozawa published this research data on figshare in April 2026.
Greater Shepparton City Council provides a dataset of playground locations within its jurisdiction. The dataset is available in multiple geospatial formats, including SHP, GEOJSON, and CSV, and was last updated on 2026-04-26. The council does not warrant the data's definitiveness or freedom from error.
NASA's ATom dataset provides atmospheric sulfur dioxide concentrations from the ATom-4 campaign in April and May 2018. Measurements were collected at 1-second intervals using a Laser Induced Fluorescence instrument capable of detecting SO2 at the single-part per trillion level. This data characterizes both natural and anthropogenic sources of SO2, a key aerosol precursor.
BOREAS TE-18 is a land cover classification image derived from a Landsat-5 Thematic Mapper scene captured on September 2, 1994, over the Southern Study Area (SSA). The classification uses a geometric optical canopy model and spectral trajectories from land cover reflectances as training data. The data product is provided in a binary image file format with companion thumbnail and utility files.
Hydrogen oxide mixing ratios measured by the Airborne Tropospheric Hydrogen Oxides Sensor (ATHOS) during the ATom 1-4 campaigns. The dataset includes simultaneous measurements of hydroxide (OH) and hydroperoxyl (HO2) using laser-induced fluorescence, along with OH reactivity data. It is provided by ORNL_CLOUD and was last updated in 2026.
Figshare hosts supplementary data from a study investigating ursolic acid's mechanism in mitigating hepatic ischemia-reperfusion injury. The research employed a murine model, network pharmacology, non-targeted metabolomics, and molecular docking to identify key pathways. Wen Hou authored the work, which was last updated in April 2026.
STEREO-A PLASTIC data provides phase space densities for Helium pickup ions (He+) and proton plasma moments from the STEREO-A spacecraft. The dataset includes 10-minute, 1-hour, and 24-hour averages of He+ densities across 51 normalized velocity ranges relative to the solar wind speed. NASA maintains this data, with the last update recorded on 2026-03-13.
A 516.8 KB PDF authored by Mohammed Ikagu Yusufu, last updated on 2026-04-11. The paper details the development of activated carbon from waste materials like coconut shells, wood, and cattle bones, focusing on process optimization and adsorption performance for chlorine removal from water.
The 2023 fire season dataset maps 12.74 million hectares of burned area in Canada's forested ecozones, representing 1.8% of the total forest-dominated area. It was developed by Natural Resources Canada using the TIIC algorithm on Sentinel-2 and Landsat time-series data. The data distinguishes between summer (11.57 Mha) and fall (1.16 Mha) fires, with fall detection limited to a 4-km buffer of official perimeters to reduce errors.
PAR data originates from optical sensors on two of 17 meteorological ODAS buoys deployed along Canada's west coast. The dataset is managed by the OB_DAAC organization for the Canadian federal departments of Environment and Fisheries and Oceans. A referenced publication from 1999 provides foundational methodology.
Dimanganese complexes featuring formal metal–metal multiple bonds are scarce. The dataset includes computational and spectroscopic analysis of the 32-electron bis-μ-phosphido complex [{Mn(CO)3(μ-PtBu2)}2] and its reduced species. This work by Preshit C. Abhyankar, last updated in April 2026, addresses the hypothesis that such bonds may act as spectators or participants in catalytic reactions.
NASA's FIRMS MODIS/Aqua Terra Thermal Anomalies/Fire locations 1km Near Real-Time (NRT) dataset identifies active fires and thermal anomalies like volcanoes. The data is processed by NASA's LANCE FIRMS using the MOD14/MYD14 swath products and represents the center of a 1km pixel flagged by the MODIS Fire and Thermal Anomalies algorithm. Collection 61 data replaced Collection 6 in April 2021, with processing changes focused on calibration improvements for the underlying Level 1B products.
A dataset from the Dutch Ministry of the Interior and Kingdom Relations describing milling infrastructure for surface water transfer. The data is available in multiple geospatial and tabular formats, including KML, ESRI SHAPE, CSV, and JSON. It is published under a CC0-1.0 public domain license.
Shiman Lin published a 5.5 KB Excel file comparing three optical sensor types. The dataset is licensed for open use under CC-BY-4.0 and was last updated in May 2026.
Scripps Institution of Oceanography collected 1,038 days of ocean temperature-depth profiles using expendable bathythermographs (XBTs) from vessels like the PRESIDENT TAFT. Data were processed into the NODC Universal Bathythermograph Output format, which records temperature at non-uniform 'inflection points' to define the thermal curve efficiently. This dataset supports the International Decade of Ocean Exploration's North Pacific Experiment and Thermal Structure Monitoring Program.
