The Water and Energy Budget-based Distributed biosphere Hydrological Model with improved Snow physics for Global simulation (WEB-DHM-SG) combined the SiB2 land surface model, the GB hydrological model, a physically based snowmelt module from SSiB3, a physically based rain-snow temperature threshold dataset, and spatial distributed river depth and width data. A modifed CaMa-Flood model based on the DDM30 routing scheme is incorporated into WEB-DHM-SG.

Information for the model WEB-DHM-SG is provided for the simulation rounds shown in the tabs below. Click on the appropriate tab to get the information for the simulation round you are interested in.

Exceptions to Protocol
Exceptions: WEB-DHM-SG does not have “2015soc-from-histsoc” simulations. This is because the current version of WEB-DHM-SG takes months to do such long time simulation. To avoid disturbance because of facility failure, it was separated into two simulations.
