As of 2019, Plasma electron density/temprature data by IMP/TEL and and solar flare spectral data by SOX are archived.
Plasma electron density with IMP / temperature with TEL
Hinotori Plasma Probes observed the equatorial topside ionosphere measuring electron density and temperature
from February 23, 1981 to June 19, 1982 (solar cycle maximum).
HINOTORI Plasma Probe Te, Tn 10-sec average data and software are archived. For more details, please see the read me file.
Solar Flare Spectra with SOX
Solar X-ray Spectrometer (SOX) data archiving project is conducted in 2017 - 2019 to retrieve X-ray energy spectra of 28 solar flares. See details here.
