Three Main Measurement Objectives

1. Global Mean Sea Surface Salinity (SSS)

2. Seasonal Cycle

3. Interannual Variations

How well are we doing?



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.



Level 1 Science Mission Requirement Baseline Mission

Minimum Mission

1 The 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

0.33 0.27

2 SSS Averaging Interval 1 Month 3 Months

3 Mission Duration At least3 Years

At least1 Year

4 Deliver data products to a NASA Distributed Active Archive Center (DAAC).Level 1a Reconstructed Unprocessed Instrument DataLevel 1b Calibrated Sensor UnitsLevel 2 Derived Geolocated SSS Level 3 Time-space averaged SSS on a standard Earth Projection
