STOFS-2D-Global Shadow is a development instance of NOAA's ADCIRC-driven STOFS-2D-Global. It is operated by the Computational Hydraulics Laboratory at the University of Notre Dame.
The system has global coverage with sub-kilometer resolution in US coastal waters. It operates once-daily, rendering a 7-day forecast beginning midnight UTC. It is also validated daily against hundreds of NOAA CO-OPS and UNESCO stations.
On this page, the Shadow's latest forecast at each of these stations is provided. Additionally, a complete archive of the system's forecasts is also given, enabling the interested user to track model performance over time and conduct detailed skill assessment.
