Planetary Plasma Sounder (PPS) has two sub-systems: i) one for natural plasma-wave observations (NPW), and ii) the other for stimulated plasma-wave experiments (SPW). The archival data are open to public for the scientific use.
All the data files from 1984 to 1988 are available. The data files are in the CDF format.

This dataset contains the electric field intensity spectrum data with a time resolution of 2 seconds taken by the NPW sub-system. Each data point consists of 512 electric-field intensities at a given frequency with the frequency range from 100 kHz to 24.3 MHz. In NPWH mode operation, NPW measured 1 component of the electric field. In NPP mode operation, NPW measured right- and left-hand circular polarized components of the electric field.

The details of the specification of the data and instrument and of the PPS experiments are described in Oya et al. (1985).
