| Abstract/Description or Keywords | The Gridded Hydrologic Model Output page provides access to gridded, 1/16-degree (roughly 35 km2) projections of hydrologic states and fluxes for four watersheds in British Columbia, Canada. The gridded data were simulated using the Variable Infiltration Capacity (VIC) model (Liang et al. 1994, 1996). The simulations are generated by forcing the VIC model using statistically downscaled global climate model (GCM) projections from the Coupled Model Intercomparison Project Phase 3 (CMIP3; Meehl et al. 2007) driven by a range of future emission specified by three separate scenarios (A1B, A2 and B1) from the IPCC Special Report on Emissions Scenarios (SRES; Nakicenovic et al. 2000). Also included is historical data generated by running the VIC model with interpolated observed climate data. The simulated data includes snow water equivalent, soil moisture, surface runoff (runoff), subsurface runoff (baseflow), and actual evapotranspiration for a region covering the Peace, upper Columbia, Fraser and Campbell River watersheds. Daily values are provided for all variables, with projected data available from 1/1/1950 to 31/12/2100 and historical data available from 1/1/1950 to 31/12/2006. For the hydrologic projections, the GCM data were downscaled to a 1/16-degree resolution using Bias-Correction Spatial Disaggregation (BCSD) (Wood et al. 2004) following Werner (2011). Application of the VIC model and the generation of hydrologic projections for the Peace, Fraser, upper Columbia and Campbell River watersheds are described in Shrestha et al. (2012) and Schnorbus et al. (2011, 2014).
