2014 Aquarius/SACD/OSST Science Team MeetingSeattle, WA, 11 November 2014
Three Main Measurement Objectives
1. Global Mean Sea Surface Salinity (SSS)
2. Seasonal Cycle
3. Interannual Variations
How well are we doing?
6G. Lagerloef, Aquarius PI
2014 Aquarius/SACD/OSST Science Team MeetingSeattle, WA, 11 November 2014
Action Items and Decisions
• Identify key scientific accomplishments, surprises, new findings, etc.
• Quantify the measurements relative to the mission requirements (See next slide)
• Determine processing version, or needed changes, to use for the “final data product” of the 3-year Prime Mission, and timetable for reprocessing (within 6 months).
• Develop plans and outline for Aquarius’ NASA Extended Mission “Senior Review” proposal.
