Fifteen spectral bands from 390 nm to 1040 nm provide calibrated top-of-atmosphere radiance measurements at a 300-meter resolution. The European Space Agency's MERIS instrument on the Envisat-1 satellite collected this data from March 2002 until contact was lost in April 2012, with products reprocessed in 2020. Each Level-1 product contains 22 files, including radiance and error estimates for each band alongside annotation data.
Indo-Pacific region data from three marginal-marine sections and deep oceanic sediments. The dataset contains biostratigraphic evidence for nannofossils and planktic foraminifera, used to analyze the Oligocene-Miocene boundary. It was published by Geoscience Australia Data and last updated on 2026-04-30.
Dinoflagellate microfossils provide a reliable method for distinguishing Late Miocene-Early Pliocene sediments from older, lithologically similar deposits. The dataset identifies species like Melitasphaeridium aequabile and Tectatodinium psilatum as diagnostic for the Bookpurnong Beds, while Apteodinium australiense indicates older Murray Group formations. This data originates from Geoscience Australia and was last updated in May 2026.
A family of selective 2D NMR methods designed to address signal overlap in 1H NMR spectra. The dataset, shared by Ralph Adams under a CC-BY-4.0 license, contains data from experiments that generate 2D J-resolved spectra for chosen spin systems. The data was last updated on 2026-04 27.
A compilation of all publicly-announced gamma-ray pulsars detected by the Fermi Large Area Telescope (LAT). The list is maintained by the LAT team and includes only detections vetted to a significance of at least 5 sigma. The data is provided by the National Aeronautics and Space Administration and was last updated on 2026-04-10.
A dataset for MATLAB implementation of lock-in functional near-infrared spectroscopy. The data consists of in-vivo measurements taken under visual stimulation conditions. It was authored by Stanisław Wojtkiewicz and is available under an Open Access (green) license.
A reference dataset from the paperswithcode platform, authored by Joseph natal, providing the magnitude of a disturbance spectrum when no correction is applied. The specific time range, data collection method, and total number of observations are not detailed in the available metadata. The dataset is associated with an Open Access (green) license, but its last update date is unknown.
Optical absorption coefficient spectrum of Parylene C thin films obtained by measuring transmittance in liquid-filled cuvettes. The data likely contains wavelength-dependent absorption values for this polymer material. James A. Guggenheim authored the associated paper.
Measured Hadamard spectrum data supports figures in a research paper on complex-amplitude single-pixel imaging. The dataset is associated with author Hong-Yun Hou and is available under an Open Access license. Its specific size, format, and update details are not provided.
Run results for NASA's Meteoroid Engineering Model simulating meteoroid strikes on the asteroid Bennu. The data is associated with author W. F. Bottke and is available via the paperswithcode platform under an Open Access license.
Spectral data supporting research on excited-state lifetime enhancement in dimyristoyl-phosphocholine nanodiscs. The data is associated with a manuscript by Philip A. Kocheril published under an Open Access license. The dataset's specific size, format, and update history are not detailed in the provided metadata.
A nomenclature abstract for the bacterial order Oligoflexales, published by Charles Thomas Parker of NamesforLife. The dataset is hosted on the Papers with Code platform and is licensed as closed. The content likely contains formal taxonomic descriptions and classification details.
A nomenclature abstract for the bacterial class Oligoflexia, emended in 2020. The dataset is published on the paperswithcode platform and authored by Charles Thomas Parker of NamesforLife. The license is listed as closed.
Spectroscopic data from the James Webb Space Telescope's MIRI instrument, targeting the protoplanetary disk designated d203-506. The data includes ON and OFF position measurements and was published in a Nature article by Berné et al. in 2023. The dataset is hosted by Ilane Schroetter of the Centre National de la Recherche Scientifique.
SAFARI 2000 Fire Emission Data provides emission ratios and factors for 13 trace gases from ten African savanna fires, measured during the 2000 dry season. The University of Montana collected this data using airborne Fourier transform infrared spectroscopy (AFTIR) aboard a Convair-580 aircraft. This dataset represents the first broad characterization of abundant trace gases in nascent smoke from this region.
NASA HEASARC provides the source catalog from the Nuclear Spectroscopic Telescope Array (NuSTAR) survey of the Extended Chandra Deep Field South. The catalog contains 49 significant sources detected in the 3-24 keV band, with redshifts from 0.21 to 2.7 and rest-frame 10-40 keV luminosities spanning (0.7 - 300) x 10^43 erg/s. This table was created in September 2017 based on observations taken between 2012 September and 2013 April.
12 years of gamma-ray data above 50 MeV form the basis for this third update to the Fermi Large Area Telescope's fourth AGN catalog. The 4LAC-DR3 version contains 3,407 high-latitude active galactic nuclei with updated spectral parameters, energy distributions, and light curves. NASA HEASARC ingested the table in February 2010 and last updated it in June 2023 using data from the Fermi Science Support Center.
722 possible optical counterparts for 370 X-ray point sources from two 10-degree fields in the ROSAT All-Sky Survey. The catalog was created by NASA researchers using optical variability analysis on hundreds of archival photographic plates to identify 256 probable matches, including active galactic nuclei, cataclysmic variables, and stars. The data table combines results from two fields, one at high galactic latitude and one at low galactic latitude.
Over 16,000 known or suspected OB stars are compiled in this all-sky catalog, extending the original Case-Hamburg surveys. The catalog contains UBV photometry, MK spectral type classifications, and radial velocities for these objects. This database was created by NASA HEASARC, with its origins in 1991 and a final table creation in September 2017.
1143 true and probable planetary nebulae and 347 possible candidates are listed in this 1992 catalog. The database was created by NASA's HEASARC in May 2001 based on the CDS Catalog V/84. It uses a standardized IAU designation system for object names based on galactic coordinates.
