Description
This project generates the long term, historical, physically based snowpack modeling data set to enhance existing National Water and Climate Center (NWCC) water supply forecasting methods by providing additional spatial context of the snowpack state that is not capture. The proposed project has two components: creation of the historical gridded data set and demonstration of near real-time capabilities. While a similar contract currently exists, this work is for snowpack modeling for additional areas and represents completely new work not covered by the current contract.
The first component is long-term historical snow state modeling (including a minimum of SWE, cold content, surface water input), encompassing water year (WY) 1980 through WY 2025 for approximately 12 model domains at 5000 square mile (approx.) each to be specified through a collaborative effort with NWCC hydrologists. Modeling domains will encompass different hydroclimatic and snowpack regimes in the mountainous Western United States where snowmelt provides most of the available surface water. High resolution gridded modeled snow water equivalent (SWE) data will then be aggregated and summarized by subbasin and elevation bands within the modeling domain. The summarized information will be passed to NWCC hydrologists for evaluation in the existing operational water supply forecasting system to determine viability of these input variables for improving water supply forecast skill.
The second component is the near real-time running of the same modeling systems and framework to support operational water supply forecasting. Thus, any product derived from gridded snow data must also be capable of supporting real-time modeling, which is defined here as the capability of delivering model results from the previous day by 8:00 am Pacific Time (24 hours latency) for all basins of interest within the modeling domains.
