About Journal of Astronomy and Space Sciences

The Journal of Astronomy and Space Sciences (JASS; J. Astron. Space Sci.) is the official publication of the Korean Space Science Society (KSSS), the most prestigious academic society in the fields of space science and space applications in Korea. JASS is an international journal devoted to the publication of fundamental and applied investigations in all aspects of spacerelated science and technology. It was launched in 1984 and is published quarterly. Each article published is assigned a unique DOI that serves to identify the article in the digital environment. JASS is an open access journal; consequently, the full texts of articles are free for all users to read and use. The papers published in JASS are accessible on the journal homepage (http://janss.kr), the DOAJ website, and the SAO/NASA ADS website. JASS has been indexed by KCI and SCOPUS since 2007 and 2012, respectively. Additionally, JASS was re-indexed by DOAJ and newly indexed in the ESCI (Emerging Sources Citation Index) by Clarivate Analytics in 2017. This journal is supported in part by a Grant-in-Aid for the publication of scientific research from the Korean Federation of Science and Technology Societies (KOFST).

The electron density profiles produced from the ionospheric sounding system are traditionally estimated by the inversion procedure based on the image analysis of the observed ionograms. Jang Bogo Vertical Incidence Pulsed Ionospheric Radar (VIPIR) with Dynasonde (hereafter, JVD), however, uses the three-dimensional electron density inversion approach named “NeXtYZ” to produce ionospheric density, ion velocity, and tilt of the ionization in the bottomside ionosphere based on the list of detected radio echoes with their physical parameters.

The tip of the Antarctic Peninsula is widely recognized as one of the most active regions for gravity wave activity. Situated in this dynamic area, the King Sejong Station (KSS: 62.22°S, 58.78°W) serves as an ideal location for investigating gravity wave activity in the mesosphere and lower thermosphere (MLT) region. The Korea Polar Research Institute (KOPRI) has been operating a meteor radar (MR) and an airglow all-sky camera (ASC) at KSS for over a decade, enabling studies on gravity wave activity and MLT dynamics. To enhance these observa...
