ABSTRACT
Global environmental problems are always characterized by multiscale patterns and processes, and this multiscale nature calls for the building of hierarchical observation facilities as well as modeling platforms with various support scales. As a key component of the global environment, the terrestrial hydrologic cycle also presents
