Active Magnetospheric Particle Tracer Explorer (AMPTE) was a three spacecraft mission, a collaboration between Germany, the UK and the USA.

This dataset collection contains summary plots of data collected by two of the three spacecraft: the Ion Release Module (IRM), supplied by Germany, and the Charge Composition Explorer (CCE), supplied by the USA.

On board the IRM:
- Magnetometer
- Plasma instrument: measures ion and electron distributions
- Plasma wave spectrometer: measures electric fields
- Ion time-of-flight spectrometer: measures charge and mass of all major ions
On board the CCE:
- CHEM (CHarge Energy Mass): measures mass and charge-state compositions as well as energy spectra and pitch-angle distributions
- HPCE (Hot-Plasma Composition Experiment): includes an ion-mass spectrometer and electron background-environment monitor

Summary plots are lower resolution than capable by the instruments and generally noisy. These are useful for an overview of datum, in order to find interesting events.
