Precipitating Electron and Ion Spectrometer (SSJ/4)

NSSDCA ID: 2003-048A-04

Mission Name: DMSP 5D-3/F16

Description

The Precipitating Electron and Ion Spectrometer SSJ/4 measures the flux of charged particles as they enter the Earth's upper atmosphere from the near-Earth space environment. It consists of four electrostatic analyzers that record electrons and ions between 30 eV and 30 KeV as they flow past the spacecraft toward the Earth. Each of two low energy detectors consist of 10 channels centered at 34 to 960 eV. The high energy detector measures particles in 10 channels centered at 1.0 to 29.5 KeV. The instruments are built by Amptek Inc. (formerly Emmanuel College) under contract from the Space Physics Division of Phillips Laboratory and calibrated at Rice University. Processing of the SSJ/4 archive data occurs onboard the satellite and at NGDC. Data have been used primarily in space physics research, for monitoring the space environment and for forecasting space weather. NOAA's National Geophysical Data Center maintains the data archive at
