 Title:
 DAILY SIMULATED RUNOFF FROM PAN-ARCTIC WATER BALANCE MODEL (Serreze, Rawlins)
 
 Description:
 Daily runoff is generated using the Pan-Arctic Water Balance Model (P/WBM)
 [Rawlins et al., 2003]. The P/WBM simulates the high-latitude water cycle
 by utilizing gridded fields of plant rooting depth, soil characteristics
 (texture, organic content), vegetation, and daily time series of precipitation
 [Serreze et al., 2003] and air temperature. Model inputs and outputs are
 defined at 29,926 grids of ~25 km (628 km^2) resolution across the Pan-Arctic
 on the Equal-Area Scalable Grid known as EASE-Grid [Brodzik and Knowles, 2002].
 The P/WBM includes a simple scheme for simulating daily changes in soil frozen
 and liquid water amounts, which is driven by air temperature, modeled soil
 moisture content, and physiographic data. The climate time series
 (precipitation and air temperature) originate from the National Center for
 Environmental Prediction (NCEP) reanalysis project [Kalnay et al., 1996], with
 the precipitation inputs described in Serreze et al., 2003.
