Helium Ions, Density, Bulk Speed, Kinetic Temp,; Hourly Averages, 1978-83

NSSDCA ID: SPHE-00350

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1978-08-17 to 1983-12-29

Description

These experimenter-supplied data from the Solar Wind Ion Composition experiment on ISEE-1 consist of Helium ion moments as determined from measurements of 4He++ ions. Each data record in the ASCII file contains the time, bulk speed, ion density, and kinetic temperature. The data are hourly averages. Major data gaps occur from 1982-Oct-05 to 1982-Dec-04, 1982-Dec-21 to 1983-Feb-08, and 1983-Mar-10 to 1983-Nov-19. The absolute density values are believed to be good to within about 20%, with relative changes good to within a few percent. The absolute uncertainties in the speed and temperature determinations are believed to be about 2% and 20% respectively. The geotail period data tend to be spotty with many zero values for density and temperature. Spacecraft position data are not included in this data set. Daily values of the ISEE-3/ICE spacecraft position in GSE coordinates are included in the magnetic field data set 78-079A-02D .
