Service Improvement
When Dr. Paul Chang flies over the Gulf of Alaska… NWP model performance improves

Requirement
Dr. Paul Chang flies over the Gulf of Alaska (and even the Bering Sea) all the time!
But seriously...

Marine and Sea Ice Forecasts

Bering Sea

All NOAA & All Hazards
• Oil and Chemical Spills– Require precise direction and speed
• Support of Fisheries and Subsistence– Sea Ice– Marine forecasts
• Coastal Erosion
![Page 11: Ocean Vector Winds, Looking Toward the Future](https://reader036.fdocuments.us/reader036/viewer/2022062321/56813fd2550346895daab4cc/html5/thumbnails/11.jpg)
Coastal Erosion
• Remotely sensed wind is necessary where ice prohibits buoys
![Page 12: Ocean Vector Winds, Looking Toward the Future](https://reader036.fdocuments.us/reader036/viewer/2022062321/56813fd2550346895daab4cc/html5/thumbnails/12.jpg)
Other Stakeholders
• Search and Rescue– USGC (even pilots use marine fx)– State Agencies
• Vessel Owners/Operators– Monitoring/tracking vessels and
weather conditions
• Insurance Companies
• Petroleum Industry

The Mantra
• Higher Resolution– Spatial– Temporal (more passes)
• Closer to the coast• Particularly key in SE Alaska
![Page 14: Ocean Vector Winds, Looking Toward the Future](https://reader036.fdocuments.us/reader036/viewer/2022062321/56813fd2550346895daab4cc/html5/thumbnails/14.jpg)
Data Quality
• Improve higher and lower wind speed
• Tighten up the directional error
• Rain contamination

GFE Compatible
• Smart Tools– Initialize wind
field
– Nudge to QuickScat
– Initialize surface pressure field
• AK GFE resolution: 3.1 to 6.2 km

Couple SAR and QuickSCAT
• Combine vector capability of QuickScat with resolution of SAR
• Use one to improve the other
