This set of plasma data came from the ISIS 2 (International Satellites for Ionospheric Studies) ion-mass spectrometer experiment. Ion densities of various ion species are available for the lower range (1-8 atomic mass units, H+, D+, He+, N++, O++) and the upper range (8-64 atomic mass units, O++, N+, O+, 18+, N2+, NO+, O2+). Also included in the data set are spacecraft position data, geomagnetic field intensity, F107 flux (daily solar radio flux), Kp indices, and Dst indices.
