History
PPARC was established in April 1999 by integrating the Upper Atmosphere and Space Research Center (established in 1973), the Onagawa Geomagnetic Observatory (established in 1957), and the observatories of the Department of Geophysics, Graduate School of Science, which had been conducting observations and research on the Earth’s upper atmosphere and magnetosphere, planetary radio waves, and variations in the Earth’s magnetic field.

Chronology
1980Kawatabi Jupiter Radio Observatory, Department of Geophysics, was newly established.
| 1932 | Mukoyama Observatory attached to the Faculty of Science (Yagiyama, Sendai) established; geomagnetic observation begins. |
| 1947 | Onagawa Earthquake and Tsunami Geomagnetic Observatory attached to the Faculty of Science was established. |
| 1956 | Night-light Observatory attached to the Faculty of Science (at the foot of Mt. Zao) was established and started sweeping sky observation of oxygen green line. |
| 1957 | Geomagnetic Observatory attached to the Faculty of Science was established. |
| 1961 | Geomagnetic Observatory moved to the present location (Kirigasaki, Onagawa) |
| 1973 | Research Institute for Upper Atmospheric Physics (Division of Upper Atmospheric Physics) was established, and the Luminous Observatory was reorganized as Zao Observatory. |
| 1974 | Radio observation of Jupiter started at Zao Observatory. |
| 1977 | Zao observatory started 1km interferometric observations of Jupiter’s radio waves. |
| 1984 | Yoneyama Jupiter Radio Observatory, Department of Geophysics, was established. |
| 1992 | Iitate Jupiter Galaxy Radio Observatory, Department of Geophysics was established. |
| 1993 | Zao observatory moved to the present location (Nanokaibara, Togatta Onsen, Zao-machi) |
| 1996 | Geomagnetic Observatory started low-frequency wave observation of lightning discharges. |
| 1996 | Iitate Jupiter Galaxy Radio Observatory 100m baseline array interferometer installed Galactic radio observation started. |
| 1998 | Iitate (Optical and Radio) Observatory, Department of Geophysics, was newly established. 60cm optical telescope (T60) was installed, and observations of Io-originating gases of Jupiter’s satellites began. |
| 1999 | Planetary Plasma and Atmospheric Research Center was established by reorganizing and integrating the High-Tc Physics Research Facility, the Geomagnetic Observatory, and each observatory. Observatory and observatories were renamed “Planetary Sphere ## Observatory” (##: Onagawa, etc.) |
| 2000 | Iitate (Optical and Radio) Observatory installs a large radio telescope (IPRT) and begins radio observations of Jupiter’s radiation belt. |
| 2000 | University of Hawaii Haleakala Observatory installed a 2-meter optical dome and started observations of Jupiter’s Io-originated gas. |
| 2006 | Installation of 2.6m optical dome and 40cm optical telescope (T40) at University of Hawaii Haleakala Observatory. |
| 2010 | Iitate (Optical and Radio) Observatory started IPRT solar radio observations. |
| 2014 | University of Hawaii Haleakala Observatory T60 was moved from Iitate (Optical and Radio) Observatory. |
