NOAA-NSF collaboration – evaluating coastal models utilizing Texas Advanced Computing Center services

The Unified Forecast System (UFS) is a proposed community-based earth modeling system that is designed to incorporate oceanographic forecast model core(s) into a simplified NOAA modeling suite. This simplification is intended to reduce the footprint of the number of NOAA models and thus reduce development, operations, and maintenance.

Model Upgrade: Global Extratropical Surge and Tide Operational Forecast System Upgraded to Version Two

Screen captures of two new implementations of version two; federal levees along the Mississippi and flood plain inclusion for Puerto Rico.

In late July 2021, the Global Extratropical Surge and Tide Operational Forecast System (Global ESTOFS) upgrade to version two was implemented into operations on the National Weather Service’s (NWS) Weather and Climate Operational Supercomputing System (WCOSS). The modeling system provides forecast guidance for combined water levels caused by storm surge and tides globally, and is to our knowledge the highest resolution global operational storm surge modeling system available today. The forecast guidance from the model is used by forecasters at NWS Weather Forecast Offices (WFO) and the Ocean Prediction Center to generate their storm surge and flood forecasts during storms, including Nor’easters along the U.S. East Coast.

NOAA’s Precision Marine Navigation data service receives first major update

The Precision Marine Navigation (PMN) program has completed the first update of its prototype navigation data service – the PMN data processing and dissemination system and PMN Data Gateway viewer. The data processing and dissemination system provides surface current forecast guidance from NOAA’s forecast systems, in a prototype marine navigation data format. The viewer allows users to visualize the predictions and discover where they are. Both the system and the viewer were updated to include data from the recently upgraded Northern Gulf of Mexico Operational Forecast System (NGOFS2).
