The model parameters used to simulate the hydrologic fluxes and states in the two data above sets are available hereon the Livneh Research Group server. These parameters represent the culmination of numerous calibration efforts including those conducted by Maurer et al. (2002), Zhu et al. (2007) at 1/8° and Tang et al. (2012) at 1/16°, as well as default parameters from the NLDAS initiative for other regions. Information on the VIC model is available here on the University of Washington page.
*Note: Since soil-parameter calibrations were done on a basin-by-basin basis, certain parameters are discontinuous across basin boundaries.
