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...

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
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
