Hubble Space Telescope imaging data with associated galaxy morphology labels derived from citizen scientist classifications in the Galaxy Zoo: Hubble project. The dataset is hosted by NASA on AWS Open Data and has no restrictions on use.
The Extreme Ultraviolet Imaging Telescope (EIT) onboard the SOHO spacecraft observes the Sun's corona. It captures images over a 45 x 45 arcminute field of view in four emission line groups: FE IX, FE X, FE III, FE XV, and HE II. Data is available from the public SOHO archive and mirror archives.
GERM (Geochemical Earth Reference Model) Reservoir Database contains compiled geochemical data for major Earth and Solar System reservoirs. It includes major element oxide and trace element abundances for chondritic meteorites, primitive Earth mantle, mid-ocean ridge basalts, and the Sun. The data was compiled by SCIOPS from well-known and respected sources in geochemistry.
South and southeast Texas experienced heavy rainfall and catastrophic flooding from 17-18 October 1998. The event, documented by UCAR/JOSS/NOAA/CODIAC, involved 20 to 30 inches of rain near San Antonio, causing flash and river floods that resulted in 31 fatalities. Data collection concluded on 19 October 1998.
Palynostratigraphy data distinguishes Late Miocene-Early Pliocene Bookpurnong Beds from similar Oligocene-Middle Miocene sediments using diagnostic dinoflagellate species. Species such as Melitasphaeridium aequabile and Tectatodinium psilatum are largely restricted to the Bookpurnong Beds, while Apteodinium australiense indicates older Murray Group correlatives. The dataset is a published external journal article from Geoscience Australia.
GWTC-3 is a parameter estimation data release from the LIGO Scientific, Virgo, and KAGRA Collaborations. It contains posterior samples for 36 gravitational-wave candidate events from the second part of the third observing run. The release includes HDF5 files with samples, metadata, configuration files, and sky localization data.
Alyssa Goodman's 2025 colloquium presentation details the dynamic 3D structure of the Milky Way over a 230-million-year solar orbit. The talk showcases data and visualizations from MilkyWay3D.org, focusing on gravitational, kinematic, and radiative processes. It frames advances in astronomical data science that enable modeling of stellar formation, supernovae, and interstellar gas evolution.
COMET Case Study 015 documents the life cycle of a low-pressure system moving from Arkansas to Illinois in 1998. The dataset provides a specific example of errors in the AVN weather model, where inherent biases led to an incorrect prediction of strong cyclogenesis over the Gulf of Mexico. It was compiled by SCIOPS for educational and research purposes.
Version 2022.0 of the Terra MODIS Level-4 global mapped Apparent Visible Wavelength (AVW) data. The dataset quantifies the spectral center of water-leaving reflectance in nanometers, produced by the OB_CLOUD organization. It is used for classifying water types and guiding chlorophyll retrieval algorithms.
Apparent Visible Wavelength (AVW) quantifies the spectral center of ocean color from water-leaving reflectance. This NASA EarthData product, version 2022.0, provides a single geophysical variable measured in nanometers for global waters. It is produced by the OB_CLOUD organization using Terra MODIS satellite data.
Suomi-NPP VIIRS Level-4 Global Mapped Apparent Visible Wavelength (AVW) Data quantifies the spectral center of ocean color across the visible range. Reported in nanometers, AVW is lower for bluer, clearer waters and higher for greener, more productive waters influenced by phytoplankton, CDOM, or sediments. Users apply AVW for water-type classification, algorithm selection, and regional change detection.
Global satellite-derived ocean color data quantifying the spectral center of water-leaving reflectance. The dataset likely contains the Apparent Visible Wavelength (AVW) variable, reported in nanometers, which indicates water clarity and composition. It originates from the Suomi-NPP satellite's VIIRS instrument and is processed by OB_CLOUD.
1-minute sampled low-resolution images of hydroxyl airglow over Davis station, Antarctica, from 2017. The data consists of 16x16 pixel arrays representing variations in a 24x24 km region of the night sky approximately 87km above Davis. Observations were made in all cloud conditions between civil twilight each year using a scanning radiometer developed at the University of Western Ontario.
AVW (Apparent Visible Wavelength) quantifies the spectral center of water-leaving reflectance across the visible range, reported in nanometers. The data is produced by the OB_CLOUD organization from NASA's PACE OCI instrument, providing a Level-3 global mapped product. It is used for water-type classification and guiding chlorophyll retrievals.
PACE OCI Level-3 Global Binned Apparent Visible Wavelength (AVW) Data, version 3.1, quantifies the spectral center of water-leaving reflectance across the world's oceans. The dataset is produced by OB_CLOUD from NASA's PACE satellite observations. AVW values, reported in nanometers, are lower for clear blue waters and higher for greener, more productive or sediment-laden waters.
Paleoclimate data from the Eocene-Oligocene transition period, focusing on atmospheric CO2 (pCO2atm) reconstructions derived from boron isotope (d11B) measurements. The dataset, archived by NOAA NCEI's World Data Service for Paleoclimatology, is associated with a 2009 study by Pearson et al. and pertains to a site in Eastern Africa.
AVW quantifies the spectral center of water-leaving reflectance in nanometers, indicating water type from clear blue to productive green/brown waters. This Level-4 mapped product from the NOAA-21 VIIRS satellite is produced by OB_CLOUD for oceanographic applications. The dataset is version 2025.0, indicating a recent processing standard.
NOAA-21 VIIRS satellite data provides a global measure of ocean color spectral shape, known as Apparent Visible Wavelength (AVW), reported in nanometers. The dataset is produced by the OB_CLOUD organization and is identified as version 2025.0. It is used for water-type classification and guiding chlorophyll retrieval algorithms.
AVW quantifies the spectral center of water-leaving reflectance across the visible range, reported in nanometers. This dataset is produced by the OB_CLOUD organization and derived from the NOAA-20 satellite's VIIRS sensor. It is used for water-type classification, algorithm selection, and regional change detection in marine environments.
Apparent Visible Wavelength (AVW) data quantifies the spectral center of water-leaving reflectance across the global ocean, reported in nanometers. The dataset is produced by the OB_CLOUD organization from NOAA-20 VIIRS satellite observations for version 2022.0. It serves as an indicator for water type, with lower values for clear blue waters and higher values for greener, more productive or sediment-rich waters.
