Ionosphere Plasma Drift and Scintillation Monitor (SSIES)

NSSDCA ID: 2003-048A-03

Mission Name: DMSP 5D-3/F16


The SSIES instrument consists of an electron sensor (Langmuir probe) and an ion sensor mounted on a 2.5 meter boom. The ion sensor is a planar aperature, planar collector sensor oriented to face the spacecraft velocity vector at all times. In addition to the Langmuir probe and planar collector which make up the earlier SSI/E sensor, the SSIES includes a plasma drift meter and a scintillation meter. The SSIES measures the ambient electron density, electron temperature, ion density, scintillations, ion drift, and the average ion temperature and molecular weight at the DMSP orbital altitude. NOAA's National Geophysical Data Center maintains the data archive at
