10-minute averaged values of solar wind alpha particle flow speed, density, thermal speed, alpha to proton density ratio, and proton-alpha flow speed difference. The data product was created by the National Aeronautics and Space Administration. It was last updated on March 13, 2026.
STEREO-B satellite beacon data from the PLASTIC instrument provides measurements of plasma and supra-thermal ion composition in the solar wind. The data is provided by the National Aeronautics and Space Administration and was last updated in March 2026. The dataset has not been validated and should not be used for publication purposes.
NASA's AMPTE-UKS satellite provides 5-second averaged ion plasma moments. The dataset likely contains measurements of plasma density, temperature, and velocity. It was last updated on March 13, 2026.
National Aeronautics and Space Administration provides ion plasma moments averaged over 5-second intervals. The data likely contains measurements of solar wind plasma properties. The dataset was last updated on March 13, 2026.
Voyager 1 Plasma Experiment averaged ion data collected during the spacecraft's encounter with Jupiter. The dataset is derived from the Plasma Science instrument and is provided in a 96-second averaged format. It was produced by the National Aeronautics and Space Administration.
Long Island Sound is a 150 km long, 30 km wide estuary with a mean water depth of 24 m. This GIS layer represents a U.S. Geological Survey interpretation of sea-floor sedimentary environments, created from sidescan-sonar, seismic-reflection, and sediment sample data. The work was conducted in cooperation with the State of Connecticut Department of Environmental Protection and the U.S. Environmental Protection Agency.
SARAL-AltiKa is a collaborative satellite mission between the French space agency CNES and the Indian space agency ISRO. Its primary instrument, AltiKa, is an innovative Ka-band altimeter system dedicated to accurate measurement of ocean surface topography. The satellite flew on the same orbit as ESA's EnviSat until at least July 2016 to ensure continuity of long-term altimetry observations.
The Wind spacecraft mission, part of the International Solar Terrestrial Physics program, measures solar wind and Earth's foreshock region. The WAVES investigation provides coverage of radio and plasma wave phenomena from fractions of a Hertz to 14 MHz for electric fields and up to 3 kHz for magnetic fields. Data is archived by the Polar-Wind-Geotail Data Archive and NASA's CDAWeb.
A magnetometer system installed at Arrival Heights, Antarctica, records two horizontal components of Earth magnetic field variations (dB/dt). The system began continuous operation in January 1989 and is maintained by personnel from the University of Newcastle. It operates in conjunction with a network of similar Australian magnetometers.
NASA's Terra satellite MODIS instrument provides 5-minute snapshots of global cloud optical and physical parameters. The data includes cloud top temperature, height, optical thickness, and particle radius derived from infrared and visible radiances. This Level-2 product is processed by the MODIS Atmosphere Team.
NASA's Aqua satellite provides Level-2 cloud optical and physical parameters derived from infrared, visible, and near-infrared radiances. The product contains parameters like cloud optical thickness and effective particle radius, with spatial resolutions of 1 km or 5 km at nadir. Each data file covers a five-minute observation interval.
NASA CDDIS provides ground-based Satellite Laser Ranging observation data in monthly files. The dataset contains unambiguous range measurements with millimeter precision from a global network of stations to satellites equipped with retroreflectors. Analysis Centers of the International Laser Ranging Service use this data to produce precise station positions and velocities.
Monthly files of ground-based Satellite Laser Ranging (SLR) observation data provide unambiguous range measurements with millimeter precision. The data is collected from a global network of stations and contributed to the NASA Crustal Dynamics Data Information System (CDDIS) by the International Laser Ranging Service (ILRS) Analysis Centers.
2000s-era data includes absolute counts and relative abundances of diatom species from sediment and water samples collected during LMG0502 and NBP0603 research cruises. The dataset, managed by SCIOPS, provides diatom counts alongside latitude, longitude, water depth, sea surface temperature, salinity, and sea ice observations. Samples are stored at the Antarctic Marine Geology Research Facility and Colgate University.
309 PNG plot images from quantum computing calibration experiments are paired with vision-language question-answer pairs. The dataset, created by NVIDIA, is designed to evaluate a model's ability to interpret and reason about experimental results. It contains 243 benchmark entries, as noted in the description.
NASA-AMES format data from a scientific cooperation between CNRS (France) and CNR (Italy) measures vertical profiles of cloud optical parameters in Antarctica. The dataset includes squared range-corrected lidar signal, aerosol backscattering, scattering ratio, and auxiliary variables like date, time, latitude, and longitude. Data was last updated on 1990-12 26 23:59:59.999000.
Two anchored instrument lines collected temperature data in the Bransfield Strait, Antarctica, each equipped with a chain of 5 thermometers and a data logger with a 262,000-word capacity. The GEBRATERM project, organized by SCIOPS, conducted this work during Antarctic campaigns, including DRAKE 95 and FRUELA, with data collection concluding in December 1995.
Chaoxu Chen published a collection of original pictures depicting optical fields after experiencing turbulence distortion and subsequent S2A mapping. The dataset is available as a ZIP file with a size of 8.2 MB. It was last updated on April 3, 2026.
Replication package for a study accepted in 2026 by the Journal of Political Economy. The data supports the analysis of peer effects and rank concerns within educational settings. It was authored by Michela Tincani.
111 seabed sediment samples from the Leveque Shelf, Browse Basin were analyzed for grain size using a laser diffractometer. This dataset supports assessments of the area's CO2 storage potential and seabed habitat mapping, collected during a 2013 marine survey by Geoscience Australia.
