抄録

We have developed the new ray tracing tools through the Japan Meteorological Agency (JMA) meso-scale analysis (MANAL) data for reducing atmospheric effects on geodetic positioning, such as Global Navigation Satellite System (GNSS), Very Long Baseline Interferometry, and Interferometric Synthetic Aperture Radar (InSAR). Our tools so called KAshima RAy-tracing Tools (KARAT) is powerful to improve accuracy of position coordinates. We will present a brief overview about the capabilities and functions of KARAT and we also present computation performance issues in the meeting.
