Interplanetary Monitoring Platform (IMP-8) Charged Particle Measurement Experiment (CPME) Data

IMP-8 continues to operate. The Charged Particle Measurement Experiment (CPME) on IMP-8 provide text-formatted data files containing energetic ion and electron count rates and fluxes that cover a wide variety of ion species, energy ranges, angular distributions, and time resolutions.

EPE data at JHU/APL consists of: - 32-Day Hourly-Average Plots Organized by Solar Cycle - plots of 5.5-minute and 1-hour averaged intensities - text files of 5.5-minute, 1-hour, and 1-day averaged intensities and count rates - Merged data with the IMP-8 Energetic Particle Experiment (EPE) Data at NSSDC consists of: - Reduced Data Files Containing Count Rates of all Detectors - Hourly Proton Flux 1,2,4,10,30,60 MeV Data - Survey Plots of all Detectors, 24-Hours of Data Per Plot, on Microfilm - Daily Averaged Fluxes - 20-s CPME + EPE Particle, 15-s Magnetic Field and 1-min Plasma Merged Data Set - Daily Averaged Proton Fluxes Greater than 10, 30, 60 MeV - Daily Averaged Flux Plots on Microfiche - Hourly Averaged 1-2, 14-25 MeV Proton Flux Data - Energetic Electrons and Protons Data - Hourly Averaged 1-2 and 14-25 MeV Proton Flux Data
