1. Aquarius Simulation Studies Algorithm Workshop 9-11 March 2010 Gary Lagerloef Aquarius Principal Investigator

2. Approach • What: Generate a set of special case 7-day cycles • Specific cases: biases, drifts, etc, in following charts • Who: ADPS with science team input • How: Use the operational mission simulator. • Start with daily files from RSS • Add spurious signal for specific case study (see below) • Input these to the mission simulator as test cases. • Distribute and analyze (science team) • Timetable: • 9 July: Produce TBD subset of scenarios (L2 files) • 19-21 July: Science Meeting Seattle – Explain approach, invite participation • July-August: Analysis • September: Assess results (special workshop?) • October: ORR

3. Scenario Flow Chart Daily simulated files (RSS & JPL) Apply spurious signals for special case studies Mission Simulator Telemetry files to/from Cordoba Generate special case telemetry files Level 1 > Level 2 > Level 3 Routine Processing Level 1 > Level 2 > Level 3 Special Case Processing Daily Mission Simulator L1, L2, L3 files uploaded to web site Special Case Simulator L1, L2, L3 files uploaded to special web site with documentation

4. Potential scenarios / rehearsals Simulate certain special situations to test and analyze Develop and test analysis tools Demonstrate we can address these issues at ORR • Insert arbitrary biases in all 12 channels • Simulate arbitrary drifts in all 12 channels • Orbit harmonics calibration drifts (1-4 harmonics, e.g.) • Simulate a complete cold sky maneuver • Solar flare • RFI • Attitude offsets • Channel failure • H or V channel • P or M channel • Other suggestions … lunar, bi-static solar reflection, diffuse galaxy refl. • Scatterometer cases to be defined (Simon & Adam?)
