The data consists of calibrated snapshots of 2048 points per channel collected every 128.8 seconds, covering an unattenuated frequency range from 20Hz to 16000Hz. The dataset is produced by NASA and referenced in scientific literature.
Plasma wave data from the Polar spacecraft's Wideband Receiver, capturing high-resolution electromagnetic field fluctuations. The instrument collected snapshots of 1992 or 3984 data points every 0.064 seconds, with a sampling frequency of 249 kHz. Data was produced by the University of Iowa and is hosted by the National Aeronautics and Space Administration.
NASA's Ocean Biology DAAC produces near real-time (NRT) phytoplankton carbon concentration data derived from ocean-color satellite observations. The carbon_phyto product provides phytoplankton carbon concentration in milligrams per cubic meter. Typical uses include quantifying biomass and carbon stocks, assessing ecosystem productivity, and driving biogeochemical models.
NASA's PACE satellite provides near real-time phytoplankton carbon concentration derived from ocean-color observations. The Ocean Biology DAAC produces this product using the best-available ancillary meteorological and ozone data for a snapshot within a single orbit. Typical uses include quantifying marine biomass and carbon stocks, assessing ecosystem productivity, and driving biogeochemical models.
The SWICS/MASS/STICS instrument package on the WIND spacecraft provides measurements of solar wind and suprathermal ions. Data includes alpha velocity, C/O abundance, ionization temperatures, and particle rates from the SWICS and STICS instruments. The dataset is part of the International Solar Terrestrial Physics (ISTP) program and is available from the University of Maryland, the Polar-Wind-Geotail Data Archive, and NASA's CDAWeb.
Meteorological data collected from three stations (BEGC, COLA, GEOD) on Deception Island. Variables include soil temperature at depths from 0 to 70 cm, soil heat flux, air temperature, wind, snow depth, and solar/terrestrial radiation. The data is recorded by SCIOPS, with measurements taken every minute during Antarctic summer campaigns and every ten minutes during winter.
The Solar Ultraviolet Measurements of Emitted Radiation (SUMER) instrument is a UV telescope and spectrometer on the ESA/NASA SOHO spacecraft. SUMER has observed the Sun from approximately 1.5 million kilometers since 1996, delivering data on plasma flows, temperatures, and magnetic activity in the solar atmosphere. The data are archived at the Max-Planck-Institut für Aeronomie and mirrored at several international institutions.
Eight consecutive days of fire data are packaged into a single file generated every eight days at 1-kilometer resolution. The Terra MODIS instrument provides this Level 3 product containing fire mask, quality indicators, maximum fire radiative power, and fire pixel position. The data is produced by LPCLOUD from the MODIS/Terra sensor.
MODIS/Terra Thermal Anomalies and Fire data provides an 8-day composite of maximum fire pixel detections at 1-kilometer spatial resolution. The product includes a fire mask and pixel quality indicators as its Science Dataset layers. It is generated by the LPCLOUD organization using data from NASA's Terra satellite MODIS instrument.
MYD14A2 Version 6.1 provides a global 1-kilometer resolution composite of maximum fire pixel classes detected over eight-day periods. The product includes a fire mask and pixel quality indicator layers, generated from Aqua MODIS satellite data. LPCLOUD processes and distributes this Level 3 gridded data.
FEMA's Multi-Hazard Mapping Initiative maintains a collection of geospatial hazard data for advisory purposes. The data includes historical North Atlantic hurricane tracks, tropical cyclone tracks, and a landslide overview map for the conterminous United States. It is provided by the organization SCIOPS via the NASA Earthdata platform.
Multiple years of national case and mortality data for hepatitis A, B, and C, stratified by jurisdiction, demographics, and risk factors. The dataset underlies the CDC's HepTracker dashboard and is sourced from the National Notifiable Diseases Surveillance System and the National Vital Statistics System. It provides counts and rates to monitor trends and inform public health programs aimed at eliminating viral hepatitis.
A 21.6 MB dataset contains synthesized and characterized data for two pairs of homochiral Cu(II) and Zn(II) complexes constructed from chiral bissalicylaldehyde derivatives. The data, authored by Chao Huang and published under CC BY 4.0, includes photophysical property measurements and thermal stability investigations of the complexes.
NASA's IMP 8 satellite collected this dataset of solar wind plasma parameters at two-minute intervals. The data likely contains measurements of plasma properties from the Interplanetary Monitoring Platform mission. It was published on datagov and last updated on 2026-03-13.
NASA research on male WAG/Rij rats subjected to simulated spaceflight stressors. The dataset includes behavioral test results from Open Field, Novel Object Recognition, and Forced Swim Test assays, linked to metabolic pathway analysis in plasma, hippocampus, and cortex tissues collected 6-9 months post-exposure. Data was last updated on March 13, 2026.
NASA's dataset examines the effects of simulated galactic cosmic ray irradiation and hindlimb unloading on Fischer 344 rats. It includes behavioral performance data from Open Field and Novel Object Recognition assays and long-term metabolic pathway analysis from plasma, hippocampus, and cortex samples collected six months post-exposure. The study was last updated in March 2026.
Geoscience Australia conducted a study from 2011 to 2014 assessing CO2 storage in the offshore Vlaming Sub-basin, covering approximately 23,000 km2. The research confirmed the suitability of the Gage Sandstone reservoir for long-term storage and provided more accurate site delineation.
From 2005-09-23 to 2017-12-31, this dataset provides in-situ water temperature and derived turbulence quantities from chipod instruments on a Tropical Atmosphere Ocean (TAO) Array mooring in the equatorial Pacific Ocean. Measurements were taken at seven specific depths between 29 and 119 meters, with data gaps present. The data, stored in NetCDF format, are intended for studying ocean mixing and thermal structure.
Edgerton, Germeshausen, and Grier, Inc. submitted these water column measurements collected from multiple ships over an eight-month period in 1972.
