Outline of Final Research Achievements

We conducted observations using a low-cost small airglow imager at various latitudes to study the feasibility of observing plasma bubbles with the imager in the low-latitude and equatorial regions. The imager was installed in different locations, including Ishigaki Island in Okinawa, Ogimi in Okinawa, Sugadaira in Nagano, Tainan City in Taiwan, Chumphon in Thailand, and Iloilo in the Philippines, to carry out observations of plasma bubbles. We compared the data obtained from the low-cost small airglow imager with data from GNSS ionospheric total electron content observations, High Frequency (HF) Doppler observations, and VHF aeronautical navigation radio wave observation systems for the observed cases of plasma bubbles. Through this comparison, we evaluated the potential of wide-area observations of plasma bubbles based on the low-cost small airglow imager.

Academic Significance and Societal Importance of the Research Achievements

低緯度および赤道付近のアジア諸国に小型大気光イメージャを展開し、短波ドップラー観測などの様々な電波観測システムと組み合わせることによって、プラズマバブルの発生が衛星測位システムに与える影響を監視するためのネットワークを構築することが可能であることが示された。このようなプラズマバブルの広域モニタリングが実現できたことは、プラズマバブルの宇宙天気への影響(例:全球衛星測位システムへの影響)を評価、予測できるようになったという点において社会的意義が大きい。
