Abstract
Remotely sensed satellite data is easier to collect and better to represent local phenomenon than a site data. So they can contribute to the activation and development of many research. However, it is necessary to improve spatial resolution suitable for application in the area of complex topography such as the Korean Peninsula. In this study, finer resolution Land Surface Temperature (LST) was downscaled from 4 km to 500 m by combining GOCI with MI data of Communication, Ocean and Meteorological Satellite (COMS). It was then statistically analyzed with LST data observed from the ASOS sites to validate its applicability. As a result, it was found that the errors decreased and correlation increased at the most validation sites, also the spatial distribution analysis showed a similar tendency but it expressed the complicated terrain better. This study suggests possibility of expanding the application range of COMS by producing finer resolution data available in various studies.
