The National Polar Research Institute (NIPR) publishes Polar sciences, a quarterly, peer-reviewed polar science journal in collaboration with Elsevier BV. The most recent special issue was titled “SuperDARN / Studies of Geospace Dynamics – Today and Future”, which focused on studies of geospatial dynamics in particular related to SuperDARN, an international high-frequency radar network for collaborative scientific research.
SuperDARN (Super Dual Auroral Radar Network) is an international collaboration project of ten countries in the world, established in 1995. Within the framework of this collaboration, a coherent international radar network at high frequency is built. More than 35 radars are currently operated by more than 15 research institutes, of which ten are located in the Antarctic region, including 2 SENSU radars at the Japanese Antarctic station Syowa. These radars are distributed from mid to polar latitudes with a wide longitudinal coverage. Their global fields of view cover considerable portions of the global ionosphere in both hemispheres.
The main scientific objective of SuperDARN was to obtain global maps of plasma convection and electric field with high temporal resolution in near real time, which had never been done before, in order to contribute to space weather research. . In addition, SuperDARN has been designed to provide fundamental and essential physical parameters in the ionosphere. Therefore, SuperDARN had to answer many upper atmosphere and geospatial scientific questions regarding a variety of ionospheric and magnetospheric phenomena, as follows:
– Magnetosphere-ionosphere coupling
– The neutral atmosphere and its coupling with the ionized atmosphere
– Influence of geospatial on the lower atmosphere and potentially global climate change
– Pure plasma physics and astronomy
– Practical applied physics, including immediate space weather and forecasts
Since the creation of SuperDARN in 1995, a quarter of a century has passed. As the number of SuperDARN research groups, radars and total fields of view increases, their fields of scientific research and their many scientific achievements continue to grow. One of the factors of this success is the lively discussions at the annual international workshops. Workshops are held in various locations each year to share and discuss important scientific research, new discoveries, current problems to be solved, and future scientific directions and collaborations.
As a founding member of SuperDARN, Japan became the host country of the workshop in 2019 (3rd SuperDARN workshop held in Japan). It was held in Fujiyoshida, Yamanashi, at the foot of Mount Fuji in Japan between June 2 and 7, 2019, hosted by NTIC (National Institute of Information and Communication Technologies), NIPR (National Research Institute polar), ISEE (Institute for Space-Earth Environmental Research) at Nagoya University, ICSWSE (International Center for Space Weather Science and Education) at Kyushu University and University of ‘electrocommunications.
“Following the success of the workshop, we proposed a special issue of the Polar sciences journal, which focuses on studies of geospatial dynamics in particular related to SuperDARN, ”said Associate Professor Akira Sessai Yukimatu of the National Polar Research Institute, editor of this special issue. new scientific results and future perspectives primarily through, but not limited to, the scientific papers presented at the workshop, while contributing to the further development of geospatial sciences and relevant technologies.
In this special issue, thirteen valuable articles have been published covering a wide variety of scientific and technical topics related to SuperDARN. “This special issue was an opportunity to commemorate a quarter of a century since the creation of SuperDARN. We believe that these papers will contribute to the further development of SuperDARN research, geospatial sciences and relevant technology, ”said Associate Professor Yukimatu. The full text of this issue is freely accessible worldwide for a limited time until February 9, 2022.
On Polar sciences
Polar sciences is a comprehensive, peer-reviewed academic journal on the polar regions of Earth and other planets, which NIPR began publishing in collaboration with Elsevier BV in 2007. The primary purpose of this journal is to educate people on polar science. Currently, more than 150 articles are submitted per year. As a result, this journal is recognized worldwide as one of the few comprehensive academic journals in the field of polar science. In addition to normal problems, Polar sciences publishes a special issue each year on a given topic in various fields.
The main characteristics of Polar sciences are summarized as follows.
- Polar sciences is an international academic journal with an impact factor of 1.389 in 2019
- Polar sciences covers 15 disciplines related to Antarctica and the Arctic, such as:
– Physics of space and the upper atmosphere
– Atmospheric Sciences / Climatology
– Oceanography / Sea ice studies
– Geology / Petrology
– Solid earth geophysics / Seismology
– Marine earth sciences
– Geomorphology / Cenozoic-Quaternary Geology
– Terrestrial biology
– Marine biology
– Animal ecology
– Polar engineering
– Humanities and Social Sciences
- Polar sciences has an open archive through which published articles are made available free of charge from ScienceDirect after an embargo period of 24 months from the date of publication.
- Printed products are also published.
- After Polar sciences became an open archive in 2016, the number of article downloads has grown rapidly since then. Currently, over 140,000 articles are used (PDF downloads and HTML views) each year.
About the National Polar Research Institute (NIPR)
The NIPR conducts extensive research through observation stations in the Arctic and Antarctic. As a member of the Information and Systems Research Organization (ROIS), NIPR provides researchers across Japan with infrastructural support for Arctic and Antarctic observations, plans and implements implements Japan’s Antarctic observation projects and conducts arctic research in various scientific fields such as the atmosphere. , the ice caps, the ecosystem, the upper atmosphere, the aurora and the Earth’s magnetic field. In addition to the research projects, the NIPR also organizes the Japanese Antarctic Research Expedition and manages the samples and data obtained during these expeditions and projects. As a core institution in polar regions research, the NIPR also offers graduate students a global perspective on originality through its doctoral program.
