  1. Ocean Vector Winds, Looking Toward the Future Aimee Fish, NWS Alaska Region Satellite Surface Vector Winds Requirements Workshop June 6, 2006

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

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

  4. World & US Economic Impacts Oil Jan-Aug 2005: 878,000 barrels/day Tankers carry crude from Port of Valdez Source: Energy Information Administration, US DOE

  5. World & US Economic Impact 1/3 of the total US fishing income Source: State of Alaska

  6. World & US Economic Impacts Shipping The Great Circle Route connects North America with Asia

  7. World & US Economic Impacts Air Cargo in Anchorage 70% of all Asia-Europe 95% of all Asia-US Source: Anchorage Chamber of Commerce

  8. Marine and Sea Ice Forecasts

  9. Bering Sea

  10. All NOAA & All Hazards • Oil and Chemical Spills • Require precise direction and speed • Support of Fisheries and Subsistence • Sea Ice • Marine forecasts • Coastal Erosion

  11. Coastal Erosion • Remotely sensed wind is necessary where ice prohibits buoys

  12. 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

  13. The Mantra • Higher Resolution • Spatial • Temporal (more passes) • Closer to the coast • Particularly key in SE Alaska

  14. Data Quality • Improve higher and lower wind speed • Tighten up the directional error • Rain contamination

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

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

  17. “Small Hat” Website Items • Northern Latitude tilt • Archive Search • Why Julian Day? • Distance Scale on graphics
