In order to investigate origin of unknown Mercury's exospheric atmosphere, ground-based optical observations have been made for Mercury's sodium atmosphere with high spatial resolution at optimum observations sites, the island of Maui, Hawaii and Alice Springs, Australia. Generation processes of Mercury's exospheric atmosphere have been examined by comparing the observation results with modeled atmospheres which have been calculated using the numerical simulation code originally developed by Tohoku University.
