  • Interplanetary Monitoring Platform (IMP-8) Goddard Medium Energy (GME) Experiment Data

    https://cmr.earthdata.nasa.gov/search/concepts/C1214614919-SCIOPS.xml
    Description:

    IMP-8 (IMP-J) was launched by NASA on October 26, 1973 to measure the magnetic fields, plasmas, and energetic charged particles (e.g., cosmic rays) of the Earth's magnetotail and magnetosheath and of the near-Earth solar wind. IMP-8 continues to operate. Energetic particle data from the IMP-8 Goddard Medium Energy (GME) Experiment provide a comprehensive basis for modulation and acceleration studies at 1 AU and a critical and unique baseline at 1 AU for ongoing studies of cosmic ray modulation and propagation in the outer heliosphere for Pioneer and Voyager investigations. These include work at New Mexico State University, the University of New Hampshire, the University of Maryland, the University of Iowa, Nagoya University, the University of Tasmania and NASA/Goddard Space Flight Center. The GME instrument has provided continuous observations extending over almost a complete heliospheric cycle from launch in October 1973 and continues to operate with few problems. When combined with the data from essentially identical Goddard experiments on IMP 6 and 7, these cosmic ray and energetic interplanetary particle observations span a period of 26 years. Data from the GME instrument span an energy range of 0.5-450 MeV Hydrogen, 2-450 MeV/nuc Helium, ions from Carbon through the Iron group from several to >100 MeV/nuc and relativistic electrons. The quality of the IMP 8 GME data in terms of particle and energy resolution, and sensitivity, for galactic cosmic ray Hydrogen (2-230 MeV) and Helium (2-450 MeV/nuc) remains comparable to that of any other cosmic ray experiment flown since 1971. Some data are available through NSSDC CDAWeb and at the GMER site at the SPDF. Data at SPDF include: - Selected instrument rates at 1 hour resolution on (pre-generated ONLY) 10-day GIF plots - Selected instrument rates at 1 hour resolution. In 90-day files with 1 file for each rate (typical length 0.1 MByte) - H and He Fluxes, plus Electrons and Rates at 30 minute resolution - H, He and Ion Fluxes, plus Electrons and Rates at 6-hour resolution - Full telemetry resolution data Data at NSSDC CDAWeb consists of: - Hourly Averaged High Energy Protons (20- 40 MeV) Data - PHAS Data: Pulse Height Data from the LED & MED - MATR Data: Pulse Height Analysis Summary - Hourly-Averaged High Energy Protons 40-80 MeV Data - CNTS Data: Count Rates from the VLET, LED, & MED Detectors

  • Interplanetary Monitoring Platform (IMP-8) Low-Energy Proton and Electron Differential Energy Analyzer (LEPEDEA) Data

    https://cmr.earthdata.nasa.gov/search/concepts/C1214614980-SCIOPS.xml
    Description:

    IMP-8 (IMP-J) was launched by NASA on October 26, 1973 to measure the magnetic fields, plasmas, and energetic charged particles (e.g., cosmic rays) of the Earth's magnetotail and magnetosheath and of the near-Earth solar wind. IMP-8 continues to operate. These experiments were designed to measure the energy spectra of low-energy electrons and protons in the geocentric range of 30 to 40 earth radii to give further data on geomagnetic storms, aurora, tail and neutral sheet, and other magnetospheric phenomena. The detectors were a dual-channel, curved-plate electrostatic analyzer (LEPEDEA - low energy proton and electron differential energy analyzer) with 16 energy intervals between 5 eV and 50 keV. They had an angular field of view of 9 x 25 deg. The detectors could be operated in one of two modes: (1) one providing good angular resolution (16 directions for each particle energy band) once each 272 s, and (2) the other providing good temporal resolution in which the entire energy range in four directions was measured every 68 s. The data set consists of distribution function and moments data taken during many magnetotail passes of the IMP 8 spacecraft (at ~200,000 km). The data are at 3-min. resolution. Other data consists of: - Color Energy-Time Spectrograms, Digital Images in GIF Format - Full Color Slides of E-T Spectrograms for Plasma Measurements - 164 Second Resolution Electron and Proton Plasma Data, CDAW - Electron and Proton Plasma Data, CDAW - DigitalProton and Electron Distribution Functions

  • Interplanetary Monitoring Platform (IMP-8) Solar Plasma Electrostatic Analyzer Data

    https://cmr.earthdata.nasa.gov/search/concepts/C1214615000-SCIOPS.xml
    Description:

    IMP-8 (IMP-J) was launched by NASA on October 26, 1973 to measure the magnetic fields, plasmas, and energetic charged particles (e.g., cosmic rays) of the Earth's magnetotail and magnetosheath and of the near-Earth solar wind. IMP-8 continues to operate. A hemispherical electrostatic analyzer measured the directional intensity of positive ions and electrons in the solar wind, magnetosheath, and magnetotail. Ions as heavy as oxygen were resolved when the solar wind temperature was low. Energy analysis was accomplished by charging the plates to known voltage levels and allowing them to discharge with known RC time constants. In the solar wind, positive ions from 200 eV to 5 keV (15% spacing, 3% resolution) and electrons from 5 eV to 1 keV (30% spacing, 15% resolution) were studied. In the magnetosheath, positive ions from 200 eV to 5 keV (15% spacing, 3% resolution) and from 200 eV to 20 keV (30% spacing, 15% resolution) and electrons from 5 eV to 1 keV (30% spacing, 15% resolution) were studied. In the magnetotail, positive ions from 200 eV to 20 keV (30% spacing, 15% resolution) and electrons from 5 eV to 1 keV (30% spacing, 15% resolution) and from 100 eV to 20 keV (15% resolution) were studied. Data consists of 12-sec magnetotail data; solar wind flow parameters, based on proton and alpha particle measurements, given at approximately 2-min resolution; and, hourly data obtained by averaging 2-min resolution solar wind data provided over the years by LANL. Magnetosheath data were excluded from the 2-min data by LANL. Data is available through anonymous ftp at NSSDC, the NSSDC ftpBrowser and some plots from the PI site at LANL. Other data include: - 1-Hour averaged Proton and Alpha Solar Wind Moments Data - Merged IMP-H and -J Hourly Averaged Solar Wind Plasma Data - High Resolution Plasma Data (PROMIS period) - 5 Minute Field and Plasma Data from UCLA - 2-Minute Proton and Alpha Solar Wind Moments Data - Hourly Averaged Solar Wind Plasma Density Velocity, Proton Temperature Data - Solar Wind Three Hour Averaged Plasma Parameters from IMP I, J, and H (1973-4) - Five-minute Plasma Parameters in the Magnetotail, Three-hour Plots and Listings.
