84-Second Electron Moment Geotail Data


Availability: Archived at NSSDC, accessible from elsewhere

Time span: 1982-10-17 to 1983-12-26


This data set consists of electron moments from the Los Alamos experiment on ISEE-3/ICE for the interval when the spacecraft made a number of passes through the geomagnetic tail. Each data record contains the date and time, the electron density (per cm**3), the flow speed (km/s), the flow azimuth (degrees; with zero degrees corresponding to anti-sunward flow and positive flow azimuths corresponding to flow towards dawn), and the maximum and minimum electron temperatures (Kelvins). The time resolution is nominally 84 seconds, but occasionally 24 seconds. Merged plasma and magnetic field data for the geotail phase of the mission are in data set 78-079A-01Q; solar wind electron moment data are in data sets 78-079A-01N and 78-079A-01O; solar wind proton moment data are in data sets 78-079A-01N and 78-079A-01P (bulk flow latitude only, at 5-minute resolution); comet Giacobini-Zinner encounter electron data are in 78-079A-01N and also in 78-079A-01R. Except for the merged plasma and magnetic field geotail data set, these data sets do not contain any spacecraft position information. Values of ISEE-3/ICE position in GSE coordinates are included with the magnetic field data from JPL (data sets 78-079A-02D and 78-079A-02O).
