AB: Since 1989 Los Alamos has fielded a series of geosynchronous satellites that carry instruments to monitor the charged-particle environment from 1 eV to several MeV. The Magnetospheric Plasma Analyzers (MPA) cover the range from ~1 eV to ~45 keV for both ions and electrons. With as many as six instruments working simultaneously at a given time, we now have over 70 satellite-years of measurements, covering more than one and a half solar cycles. MPA observations have produced a rich harvest of scientific knowledge, in areas ranging from plasmasphere structure and refilling to storm-time ring current physics. The database will be described briefly, and some significant applications will be presented.
