11 inches of rainfall in south-central Kansas caused record flooding on four major rivers in October 1998. This case study documents the meteorological event, associated flash flooding, and its impacts. The dataset was compiled by SCIOPS and last updated in November 1998.
COMET Case Study 011 documents the Fort Collins, Colorado flash flood event of July 28-29, 1997. The dataset analyzes backbuilding echoes that prolonged rainfall, intense precipitation, and urban runoff complexities leading to an extreme hydrologic response. It was compiled by SCIOPS and published via UCAR/JOSS/NOAA/CODIAC.
COMET Case Study 002 documents a challenging midwest snow event primarily on 6 December 1995. The dataset was compiled by UCAR/JOSS/NOAA/CODIAC for the SCIOPS organization. It focuses on subtle atmospheric dynamics rather than a classic super-storm system.
Taxonomic and distribution data for Asteroidea (sea stars) collected from Antarctic and Subantarctic regions. The dataset comprises information on 1800 specimens identified across 5 collections. It was created at the Marine Biology Laboratory of the Free University of Brussels and published in 1989.
6,435 predicted close approaches of asteroids within 0.10 astronomical units of Earth. The data originates from NASA's Jet Propulsion Laboratory Center for Near Earth Object Studies Close Approach Data system and covers the period from 2024 to 2026.
The UltracoolSheet contains over 3000 ultracool dwarfs and imaged exoplanets. It includes photometry, astrometry, proper motions, parallaxes, multiplicity data, and spectroscopic classifications. The catalog is maintained by researchers including Will Best and was compiled from multiple papers, with a first public release dated April 15, 2015.
Data from NASA's OrbView-2 satellite, collected until its failure in December 2010, provides near real-time ocean color products. The dataset includes level 1A raw radiance counts from eight spectral bands and level 2 derived products like chlorophyll-a concentration and turbidity. It is produced by NOAA CoastWatch under the Department of Commerce.
A cleaned and restructured version of the 'hermes_reasoning_tool_use' dataset. The original multi-turn format with embedded tool call tags has been converted into a strict multi-turn conversation structure with validated role transitions. The dataset was created by AmanPriyanshu and last updated on February 24, -0026.
A dataset from the OpenML platform with the identifier 'visualizing_galaxy'. No information is available on its contents, size, or structure.
Encompassing theoretical data related to the Relativistic Contraction-Shrinking Theory (RKST), authored by Johannes Schenk. The theory proposes an emergent gravitational constant and a reinterpretation of cosmic acceleration as vacuum contraction, validated against solar-system tests and galactic dynamics from the SPARC sample.
Raman spectroscopy datasets and processed CLS analysis support a manuscript investigating alginate hydrogel detection in tissue samples. The data was contributed by author Monireh Pourrahimi and hosted by Harvard Dataverse, with a last update recorded in March 2026.
Exoplanet data published on the Kaggle platform. The dataset's specific contents, such as the number of confirmed planets or the observational features recorded, are not detailed in the available metadata. Further verification after download is required to assess its scale and scientific utility.
NASA's Cassini spacecraft recorded photometric observations of stellar occultations by Saturnian rings, satellites, and atmospheres, as well as the Jovian atmosphere. The dataset, last updated in March 2026, is a time series of brightness measurements from the Ultraviolet Imaging Spectrograph (UVIS) instrument. These observations provide a direct method for probing the structure and composition of celestial bodies by measuring how they block light from distant stars.
NASA's dataset tracks Near-Earth Asteroids (NEOs), focusing on their orbital parameters and potential hazard classification. The dataset likely contains orbital elements and hazard metrics for objects that pass close to Earth. The original source is NASA, but the specific time range and update frequency are unknown.
AGEL HST Postage Stamps contains PNG image mosaics captured by the Hubble Space Telescope (HST) for the AGEL survey. Created by Courtney Watson and managed by Observational Data, the collection provides visual representations of astronomical observations updated as of March 2026.
CASSINI UVIS Solar Stellar Brightness Time Series 1.2 contains photometric observations from the Cassini spacecraft's Ultraviolet Imaging Spectrograph (UVIS). The data records stellar occultations by Saturn's rings, satellites, and atmospheres, as well as the Jovian atmosphere. It is provided by the National Aeronautics and Space Administration (NASA) and was last updated in March 2026.
Edited digital image data records from the International Halley Watch (IHW) trial run observing Comet Crommelin. The observations were conducted largely during February and March of 1984 in preparation for the concerted international study of Comet Halley. The dataset is provided by the National Aeronautics and Space Administration.
Posterior sample files and data products from the 2021 study 'A NICER View of the Massive Pulsar PSR J0740+6620 Informed by Radio-Timing and XMM-Newton Spectroscopy' by Riley et al. The associated repository includes numeric model files, telescope calibration products, Python model modules using the X-PSI framework, and Jupyter analysis notebooks. The work was submitted to the Astrophysical Journal Letters.
A critical review paper examines the current status of cosmological nucleosynthesis, focusing on the inferred primordial abundances of deuterium, helium-4, and lithium-7. The analysis compares these abundances with the baryon-to-photon ratio determined from cosmic microwave background observations, finding overall concordance within a specific range. The paper discusses constraints on the effective number of neutrino species and other new physics.
Rhea-RT simulation movies visualize the dynamical impact of conditions in the Milky Way's Central Molecular Zone on interstellar gas and stellar feedback coupling. The dataset supports the 2026 publication by Robin Tress and colleagues. It provides visual outputs from specialized hydrodynamic simulations.
