Summary
The overarching aims of this project are three-fold. The first is to introduce enhancements to Noah-MP to remedy the key deficiencies of Noah-MP LSM identified by the UTA team. The second is to discern optimal combination of these enhancements that will maximize the skills of UFS S2S model for predicting major hydrometerological events in recent years over the western and southwestern US. The third is to experimentally couple the UFS S2S with National Water Model (NWM) to gauge the skill gains in streamflow predictions. The specific enhancements will include a new snow parameterization scheme, new initialization suites, and improved vegetation phenology. These enhancements will be experimentally introduced to the Common Community Physics Package and will undergo testing through hindcast experiments that focus on time windows associated with large deficit in snowmelt runoff in the Colorado River Basin, intensification and removal of drought conditions over the western and southwestern US
