Plasma waves, sounder, and electron number density data from Ohzora (EXOS-C) and Jikiken (EXOS-B) released

These days, it is getting common that data taken by scientific satellite are archived, and that the data source is required to be expressed explicitly for publication in academic journals. On the other hand, for the past scientific satellites whose project teams were terminated, the data products were often dead-stored in magnetic tapes or old storages in project member's laboratories. Therefore, ISAS is trying to collect those data taken by past ISAS missions and kept in Japanese universities, and release them from DARTS. Plasma waves, sounder, and electron number density data from the Jikiken (launched in 1976) and Ohzora (launched in 1984) satellites, which had been dead-stored for long time, were converted into Common Data Format (CDF), and archived in DARTS, in collaboration with Tohoku university. These data are now released via DARTS/Ohzora and DARTS/Jikiken. They can be displayed, e.g., by Autoplot and SPEDAS as shown in the right-hand side (typical example of echoes from topside ionosphere detected by Ohzora sounder). (May 2017)
