Gridded Fields of Major Water Balance Components for the World Water Development II

Fields are input to (ie., precipitation) or output (Ii.e., evapotranspiration, runoff, discharge) from the Water Balance Model (Vorosmarty et al., 1998) with improved interception function as recommended by Federer et al. (2003). Model climate inputs were from Mitchell et al. (2003).

Monthly evapotranspiration computed using Shuttleworth and Wallace (1985) PET estimates (Vorosmarty et al, 1998) and limited by modeled soil moisture. River flow was computed as flow accumulated runoff along a 30-minute resolution digital river network (Fekete et al., 2001, Vorosmarty et al, 2000a,b). Blended river flow represents a composite of observed and modeled river flow.
