5 5 G. Lagerloef, Aquarius PI 2014 Aquarius/SACD/OSST Science Team Meeting Seattle, 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?

6 6 G. Lagerloef, Aquarius PI 2014 Aquarius/SACD/OSST Science Team Meeting Seattle, 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.

7 7 G. Lagerloef, Aquarius PI 2014 Aquarius/SACD/OSST Science Team Meeting Seattle, WA, 11 November 2014 Level 1 Science Mission Requirement Baseline Mission Minimum Mission 1The Aquarius Mission shall collect the space-based measurements to retrieve Sea Surface Salinity (SSS) with global root-mean-square (rms) random errors and systematic biases no larger than 0.2 psu on 150 km by 150 km scales over the ice-free oceans 0.330.27 2SSS Averaging Interval1 Month3 Months 3Mission DurationAt least 3 Years At least 1 Year 4Deliver data products to a NASA Distributed Active Archive Center (DAAC).
