资源简介：
Global gridded fields of long-term average (1950-2000) water balance
components. 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. Land cover was
represented by potential vegetation (Melillo et al., 1993) overlain with
agricultural land cover (Ramankutty and Foley, 1999).
