CHALLENGES AND ASSESSMENTS
• In some sense ocean measurements from space are“overdue” for transition from research to operations.
Summarizing the near future “infrastructure” for ocean remotesensing:
• Ocean color - transition not secure due to technicalproblems on NPP/VIIRS instrument
• Sea Surface Temperature - transition secure with NPP,NPOESS and foreign partners
• Ocean Vector Winds - transition not secure (Quikscat 9years on orbit!)
• Ocean Surface Topography (sea level) - transition nearlymade. National need to “seal the deal” withimplementation of Jason-3 in FY10.
• WE HAVE MADE MUCH PROGRESS, BUT WE RISKLOSING CRITICAL CAPABILITIES.
