VIC-WUR Routing Forcing File
VIC-WUR requires a NetCDF file with gridded forcings. Forcing timesteps can be each model timestep (STEP), each day (DAY) each month (MONTH), or each year (YEAR). The required forcing variables and units are listed below and must also be specified in the Global Parameter File. Each forcing variable is supplied to VIC-WUR in one or multiple NetCDF files.
