| Research Abstract |
In this study, a model was developed to investigate the regional water cycles over the Shikoku District in Japan using the global positioning system (GPS) data. Data of GPS-derived precipitable water vapor were analyzed to estimate the time-scale on which the water is exchanged between lands and the atmosphere. Relation of GPS-PWV to precipitation was also analyzed as a case study. Spatial distribution of potential evapotranspiration was clarified along with topographic elevation and solar radiation over the study area.
