GPSで代表される衛星測位システム(GNSS: Global Navigation Satellite System)の測位電波が衛星から地上に到達する間に大気・電離圏で生ずる伝搬遅延は、測位の誤差要因である。GNSS気象学は、この測位誤差から大気情報を抽出する新しい大気計測法であり、近年注目を集めている。特に、集中豪雨に関係する水蒸気の空間分布と時間変動を精密観測する研究に注目が集まっている。



本ワークショップの主題であるGNSS気象学は、電波を利用した大気圏計測、及び現在の重要な宇宙システムであるGNSSに関わっており、生存圏科学の2つのミッションを基礎にしている。ワークショップでは、GNSS受信システムのH/W開発、信号・データ処理アルゴリズム開発、測位衛星データ利用等の幅広いコミュニティからの参加により、GNSS気象学の現状と将来指針に関する有益なBrain stormingが行われた。
