Impact of spatio-temporal scales on eco-hydrological changes in advanced process-based model
Process-based NICE (National Integrated Catchment-based Eco-hydrology) was further extended to include up-scaling process through coordinate transformation from rectangular coordinate system to longitude-latitude coordinate system applicable to global scale by implementing map factor and applying nonuniform grid. This improved model was applied to Hokkaido Island in northern Japan which consists of major 13 catchments. The simulated result of eco-hydrological process after up-scaling corresponded reasonably to that in catchment or sub-catchment scales. The author further evaluated the effect of map factor on hydrologic change there. This simulation system would play an important role in the improvement in biogeochemical activity in spatio-temporal hot spots and boundless biogeochemical cycle along terrestrial-aquatic continuum for global environmental change.
