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

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.
