The 8.3 KB XLSX file contains data underlying a figure and table, published under a CC-BY-4.0 license by Saif-alnasr H. Mohammed on figshare. It was last updated on May 5, 2026.
November 1978 to April 1981 data from the Imaging Proportional Counter aboard the Einstein Observatory (HEAO-2). The database contains photon event lists from a high-resolution X-ray telescope. This is a service provided by NASA HEASARC.
Abhishek Nanda's 2026 dataset provides Python code and output data for topology optimization of 3D polymer integrated optics. The 16.4 KB ZIP file contains results for designs discussed in a referenced figure, including extinction ratio (ER) and insertion loss (IL) metrics. This data is intended to enable validation and reproducibility of the reported inverse design methods.
Linearly interpolated solar wind plasma data from the ISEE-3 spacecraft, processed to a uniform 60-second resolution in GSE coordinates. The data set was constructed by Dr. J.M. Weygand for Prof. R.L. McPherron under National Science Foundation grants. It was primarily used for superposed epoch and cross-correlation studies of solar wind phenomena.
Cheshire and Worcester basins in the UK contain a vector contour dataset of estimated theoretical geothermal resources, measured in GJ/m² or PJ/km², for resource temperatures exceeding 40°C. This 'heat-in-place' data represents the amount of heat contained in productive parts of the Permo-Triassic sedimentary aquifers. The dataset is derived from a 1995 British Geological Survey technical report and the European Geothermal Atlas.
A vector contour dataset from the British Geological Survey represents the theoretical potential 'identified resources' for hot sedimentary aquifers in Permian formations. The data, derived from legacy models and a 1995 atlas, includes estimated recoverable heat values in GJ/m2, PJ/km2, and MW/km2 for resource temperatures greater than 40 °C. It covers the Collyhurst Sandstone Formation in the Cheshire Basin and the Bridgnorth Sandstone Formation in the Worcester Basin.
British Geological Survey (BGS) vector contour data representing calculated temperature distribution at the base of the Permo-Triassic in the Cheshire and Worcester basins. The dataset, derived from the 1995 UK Geothermal Catalogue revision, shows temperatures ranging from 8.0 °C to 104.6 °C. It is used as a basis for determining the heat resource potential of hot sedimentary aquifers.
British Geological Survey legacy models estimate the theoretical geothermal potential of hot sedimentary aquifers in the Sherwood Sandstone Group across four UK basins. The vector contour dataset provides identified resources in GJ/m² and recoverable heat in MW/km² at a 100-meter resolution for temperatures above 40°C. This data is derived from the 1995 Atlas of Geothermal Resources in Europe and updated for methodological consistency with a 2023 study.
103.7 °C is the maximum temperature recorded in this vector contour dataset mapping geothermal heat potential in UK sedimentary basins. The British Geological Survey created these maps based on temperature data from the 1977-1991 Geothermal Energy Programme. It covers the Permo-Triassic Cheshire, Wessex, Worcester, and East Yorkshire-Lincolnshire basins.
NASA's Solar Dynamics Observatory Extreme Ultraviolet Variability Experiment provides Level 4 model spectra. The data consists of 1,440 spectra per UTC day, derived from ESP quadrant diode irradiance and GOES X-ray channel ratios. The Laboratory for Atmospheric and Space Physics in Boulder, Colorado created these files, which model quiet sun, active region, and flare spectrum contributions.
NASA's Magnetospheric Multiscale mission provides ion composition data from its Hot Plasma Composition Analyzer. The instrument measures counts for five ion species across 63 energy levels and 16 azimuthal directions every 10 seconds. Data covers protons, alpha particles, helium ions, singly charged oxygen, and background counts in the energy range from 1 eV to 40 keV.
Hot Plasma Composition Analyzer (HPCA) data from NASA's Magnetospheric Multiscale (MMS) mission measures ion counts for five species. The Level 2 survey product provides counts for protons, alpha particles, helium ions, and oxygen ions across 63 energy levels and 16 azimuth angles, with a nominal 10-second acquisition period. Data is provided by the National Aeronautics and Space Administration and was last updated in March 2026.
NASA's Magnetospheric Multiscale (MMS) mission provides time-of-flight counts for five ion species in Earth's magnetosphere. The Hot Plasma Composition Analyzer (HPCA) instruments measure plasma energy and composition across 63 energy levels, 16 elevation anodes, and 16 azimuths. Data is collected in 10-second survey mode intervals and processed to Level 2.
Hot Plasma Composition Analyzer (HPCA) data from the Magnetospheric Multiscale (MMS) mission measures ion counts in near-Earth space. The dataset provides counts for five ion species (H+, He++, He+, O+, background) across 63 energy levels, 16 elevation anodes, and 16 azimuths, collected every 10 seconds. It is produced by the National Aeronautics and Space Administration and was last updated in March 2026.
Bio-optical validation observations were made on the CCGS Hudson from 9 May to 11 June 1997 in the Labrador Sea. Stations were occupied along several sections between Labrador and Greenland, with the most heavily sampled SW-NE section being the AR7 line of the World Ocean Circulation Experiment. The dataset is provided by the OB_DAAC organization.
This dataset provides a merged 0.5-degree gridded climatology of total lightning flash rates from two satellite sensors: the Optical Transient Detector (OTD) and the Lightning Imaging Sensor (LIS) on TRMM. The long LIS record provides detailed data for the tropics and subtropics, while OTD covers higher latitudes. It is produced by the GHRC DAAC and includes monthly and seasonal climatologies in HDF and netCDF-4 formats.
1995 to 2014 global climatology of total lightning flash rates on a 0.5-degree grid. Data is synthesized from two spaceborne sensors: the Lightning Imaging Sensor (LIS) on the TRMM satellite and the Optical Transient Detector (OTD) on OrbView-1. The dataset is produced and hosted by NASA's Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC).
