| Research Abstract |
This research project is concerned with GPS meteorology, which utilizes satellite positioning data, represented by GPS and QZSS (Quasi Zenith Satellite System), to the studies of the atmosphere. We carried out research in the following three themes:1) retrieval of high-resolution temperature and water vapor profiles obtained by the GPS radio occultation (RO) mission with small LEO (low Earth orbit) satellites, 2) evaluation of the forecast improvement by assimilation of both GPS-RO and ground-based GPS-PWV (precipitable water vapor) data into a numerical weather prediction model, and 3) analysis of time and space variations of atmospheric structure and disturbance
