New Opportunities for Wind Observations
• Instrumented Tall Towers
• Offshore wind observations & platforms (through offshore energy lease agreements)
• SODAR/LIDAR from research testbeds
• Satellite-based LIDARs
• New partnerships with the wind enterprise to share resources

Looking Toward the Future
• Stakeholder Interaction– Coordination on NOAA/Wx Enterprise Roles– Enterprise requirements for observations, model
outputs and generalized products– Populating the WIDB/4D Data Cube– Partnering to leverage existing observations – Metadata!
• NOAA Activities– Participate on OFCM/CIOS and AMS
Committees/APTs– Mission-oriented gap analysis/Tactical
deployment for gap filling– Improve analyses & models
