Five ion species—protons, alpha particles, helium ions, singly charged oxygen, and background counts—are measured by NASA's MMS spacecraft instruments. The Hot Plasma Composition Analyzer (HPCA) captures energy and composition data for magnetospheric plasmas from 1 eV to 40 keV. Data is structured as arrays of counts across 63 energies and 16 elevation anodes, acquired every 10 seconds.
MERRA-2 M2IMNXGAS is an instantaneous 2-dimensional monthly mean data collection for aerosol optical depth analysis. The dataset is produced by NASA's Global Modeling and Assimilation Office using the GEOS model version 5.12.4. It covers the period from 1980 to the present, with a latency of approximately three weeks after the end of each month.
1980-present monthly diurnal means of aerosol optical depth assimilation produced by NASA's Global Modeling and Assimilation Office. The data consists of instantaneous 2-dimensional fields averaged every three hours, generated using the Goddard Earth Observing System Model version 5.12.4. It is updated with a latency of approximately three weeks after the end of each month.
M2TMNPTRB is a 3-dimensional monthly mean data collection from NASA's MERRA-2 atmospheric reanalysis. It contains assimilations of turbulence diagnostics, such as total scalar diffusivity and Richardson number, on 42 pressure levels. The dataset covers the period from 1980 to the present and is produced by NASA's Global Modeling and Assimilation Office.
Five ion species—protons, alpha particles, helium ions, singly charged oxygen, and background counts—are measured across 63 energy levels and 16 azimuths every 0.625 seconds. The Hot Plasma Composition Analyzer (HPCA) instruments on the Magnetospheric Multiscale (MMS) mission capture this data in the 1 eV to 40 keV energy range. NASA produced this Level 2 survey data, last updated in March 2026.
Five ion species—protons, alpha particles, helium ions, singly charged oxygen, and background counts—are measured across 63 energy levels by the MMS Hot Plasma Composition Analyzer. The National Aeronautics and Space Administration instrument collects data every 10 seconds, corresponding to half a spacecraft spin period, across 16 elevation anodes and azimuths. This Level 2 survey data provides processed moments for analyzing plasma composition in the 1 eV to 40 keV energy range.
MAVEN STATIC instrument data provides time-ordered event rates summed over a single spacecraft spin. The data originates from the Supra-Thermal And Thermal Ion Composition instrument aboard NASA's MAVEN orbiter. The collection is maintained by the National Aeronautics and Space Administration and was last updated on March 13, 2026.
Five ion species—protons (H+), alpha particles (He++), helium ions (He+), singly charged Oxygen (O+), and background counts—are measured at 63 energy levels. The Hot Plasma Composition Analyzer (HPCA) on the MMS mission records data for 16 elevation anodes and 16 azimuths every 0.625 seconds. This Level 2 burst mode dataset is produced by the National Aeronautics and Space Administration.
Five ion species—protons, alpha particles, helium ions, singly charged oxygen, and background counts—are measured across 63 energy levels every 0.625 seconds by NASA's MMS spacecraft. The Hot Plasma Composition Analyzer (HPCA) instruments capture data for 16 elevation anodes and 16 azimuths per half-spin period, covering an energy range from 1 eV to 40 keV. This Level 2 survey data is produced by the National Aeronautics and Space Administration and was last updated in March 2026.
Daniel G. MacDonald's research dataset investigates the appropriate scale range for applying the gradient Richardson number (Ri) to stratified shear turbulence. It uses spectral and energetics arguments to define a fundamental shear length scale (lS) and evaluates findings against various data. The dataset is a 9.2 KB CSV file shared under a CC BY 4.0 license.
Level 2 data from the ACE spacecraft's SWEPAM instrument provides 64-second averages of solar wind ion parameters. Parameters include proton density, temperature, flow speed, velocity vectors in multiple coordinate systems, and the alpha to proton density ratio. The data are produced by NASA and are accessible via FTP in HDF, CDF, and ASCII formats.
European Anaplasma phagocytophilum genomes sequenced by Clotilde Rouxel and published in 2026. The dataset contains 12 new genomes, including four from humans and eight from cattle, doubling the number of publicly available European genomes for this bacterium. It was created using a capture-based short-read sequencing approach on samples from naturally infected hosts.
224.9 KB of CSV data from the NUTRIHEP study, authored by Caterina Bonfiglio and last updated in April 2026. This dataset likely contains dietary intake data to assess the effect of anthocyanins on metabolic dysfunction-associated steatotic liver disease (MASLD) risk. The cohort is based in Southern Italy.
558 radio sources detected at 3 GHz in the Lockman Hole North region using the Karl G. Jansky Very Large Array. The catalog includes spectral index estimates, source counts, and cross-matches with X-ray, optical, infrared, and redshift catalogs, classifying sources as radio-loud AGN, radio-quiet AGN, or star-forming galaxies. NASA HEASARC created this table in April 2017 based on observations from 2012.
The XMM-Large Scale Structure survey contains more than 6,000 X-ray point-like sources detected by the XMM-Newton Observatory over 11.1 square degrees. This table provides spectroscopic and/or photometric redshifts for 4,206 of these X-ray selected sources which have optical counterparts and have been classified by the authors. The table was created by the HEASARC in September 2013 based on a CDS catalog.
A tertiary referral medical center collected electrogustometry (EGM) thresholds at four stimulus durations and chemogustometry measurements from taste strips. The dataset includes 212 non-smoking participants aged 10 to 80 years, divided into eight age groups, with a subset of 132 participants undergoing chemogustometry. Pavlos Pavlidis from G. Papanikolaou General Hospital authored the study, which concluded EGM better documents age-related gustatory decline than chemogustometry.
Numerical simulation results for thermal management in a 16-cell lithium-ion battery pack using phase change material (PCM) and air cooling. The dataset includes time-dependent temperature variation, outlet temperature profiles, and liquid fraction of PCM for different geometric configurations under varying air velocities. Simulations were performed using ANSYS Fluent by RACHIT CHAUHAN and last updated on 2026-04 21.
Basic registrations are official government datasets mandated for use across public agencies. This dataset references the versions of ten basic registrations, specifically noting that the municipality of Oss offers two as open data: the Basic Registration Addresses and Buildings (BAG) and the Basic Registration Large-scale Topography (BGT). The data is provided by the Ministerie van Binnenlandse Zaken en Koninkrijksrelaties.
