Outline of Annual Research Achievements

・名古屋大学で保有しているが受光部が故障している高感度全天カメラ1式の受光部を、新しく安価な高感度カメラに交換、この自動観測ソフトを開発し、感度校正を行った。このカメラは、ウクライナに設置する予定であったが、令和4年2月に始まったウクライナ危機のため、設置が難しくなった。代替の場所として、ドイツ南部の観測所に設置する方向で現地研究者と交渉を進めている。
・WATEC社の小型CCDカメラを使った小型全天カメラを5式製作した。うち2式は令和4年夏にナイジェリアのアブジャ観測点に設置され、自動定常観測を継続している。但し小型カメラのために透過波長帯を広くせざるを得ず、街明かりの漏れ込みのためにデータの質はよくない。今後、より街明かりの少ない観測点への移設を検討している。残りの2台はエチオピア、タイにそれぞれ送って、現地での設置を待っている。さらにZWO社の小型CMOSカメラを使った小型全天カメラも5台製作した。うち3台はエジプトのエジプト日本科学技術大学に送って、現地での設置を待っている。
・既存のカナダ、北欧、アイスランド、アラスカ、日本、インドネシア、タイ、オーストラリアなどの観測点における光学・電磁場計測器による観測、北海道陸別のSuperDARNレーダー、ノルウェーのナトリウムライダーの計測を維持・継続した。ノルウェーのナトリウムライダーはコロナ禍で停止していたが、令和4年度末に再立ち上げを行った。ロシア、フィリピンのFM-CWレーダーやロシアの光学・電磁場機器はコロナ禍やウクライナ危機のために観測が停止している。これらの観測データとGNSS衛星電波受信器網のデータのデータベース化を行った。
・これらの地上観測データをあらせ衛星などの衛星データやモデリングと比較した解析を実施し、得られた成果を国内外の学会・研究会で紹介・発表した。

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

コロナ禍やウクライナ危機により、一部の観測が実施できていないが、既存のカナダ、北欧、アイスランド、アラスカ、日本、インドネシア、タイ、オーストラリアなどの観測点における光学・電磁場計測器による観測、北海道陸別のSuperDARNレーダー、ノルウェーのナトリウムライダーの計測を維持・継続できている。また、ノルウェーのナトリウムライダーはコロナ禍で停止していたが、令和4年度末に再立ち上げた。これらの観測データとGNSS衛星電波受信器網のデータのデータベース化を行った。また、また、小型カメラを開発し、上記のようにいくつかの海外観測点に送付を開始できている。さらにこれらの地上観測データをあらせ衛星などの衛星データやモデリングと比較した解析を実施し、得られた成果を国内外の学会・研究会で紹介・発表している。

Strategy for Future Research Activity

令和4年度には、小型カメラを中心とした観測を新たにエチオピアやエジプトで立ち上げていく。また、既存のカナダ、北欧、アイスランド、アラスカ、日本、インドネシア、タイ、オーストラリアなどの観測点における光学・電磁場計測器による観測、北海道陸別のSuperDARNレーダー、ノルウェーのナトリウムライダーの計測を維持・継続する。前年度に引き続き、これらの新しい観測データや、GNSS衛星電波受信器網のデータのデータベース化を行う。さらに、これらの地上観測データをあらせ衛星などの衛星データやモデリングと比較した解析を実施し、研究成果を上げていく。得られた成果は国内外の学会・研究会や国際誌に論文として紹介・発表し、さらに共同研究を発展させる。
