Introduction


Cryospheric Environment Simulator(CES) is a large, state-of-the-art facility available for domestic and international cooperative use. CES has the capability to reproduce the natural cryospheric environment, including simulation of a natural snowfall. This unique facility allows us to conduct many projects on basic and applied disaster mitigation studies concerned with the cryospheric environment.
