VIC infrastructure developmentsParallelization:Allows VIC to run on multiple processorsAllows VIC to run alongside the ocean modelSignificantly reduces model runtimeStandardized output and state files (NetCDF)In-progress: multiple output streamsModel simulationsOffline simulationsLong-term simulations (from 1948-)Interpolated to RASM gridBased on Sheffield et al. 2006
