  22. Aquarius/SAC-D data downlink strategy comprises multiple, overlapping downlinks each day of Aquarius science high-rate data (HRD) and Aquarius and SAC-D housekeeping telemetry (HKT). 3 to 5 passes per 24 hours over the Cordoba ground station. 1 pass per week over Matera ground station, which is transferred to Cordoba after pass. 6 - 11 minutes per pass. Downlink full science memory of 110 MB at 4Mbps (just under 4 minutes), repeating throughout pass. ADPS automatically acquires downlinks from the CUSS (separate files for Science, SAC-D/HKT) after each pass. Orbit Products including Ephemeris files are generated daily by the CODS and acquired (Two-line Elements, Predicted Ephemeris and Orbit Ephemeris, Ground Station Contacts, Ground Station Contacts Details, SAA Passes, Eclipses, Events, Maneuvers List) All files are ingested and cataloged automatically after acquisition, and made available for processing.

  24. Aquarius Data Processing Development Philosophy: 1- Maintain Flexibility - things WILL change 2- Strive for maintainability of code and documentation 3- Testing, Testing and more Testing: Get the mechanics right so that when data starts to flow, you can focus on the science Approach: 1- Use of rapid prototypes evolving into ever more realistic full-mission simulations 2- Verify that all requirements are being met 3- All components of the system are being thoroughly exercised 4- use of "real-world" testing of the end-to-end system on a routine basis - don’t just test for success Implementation: 1- Start with a full end-to-end data flow description 2- Break into the component parts 3- Use as close to real data and operational software as possible 4- Continuously evolve the simulation to add more credible data, software and interfaces as they become available Result: 1- All the supporting infrastructure, tools and procedures can be developed, tested and refined as the process continues 2- Through this modular, flexible approach, the entire system can gradually evolve to a higher and higher level of fidelity until you have as close to a fully tested and functional launch-ready system as possible prior to launch

  26. The Aquarius science data processing consists of the following steps: Level-0 Preprocessor – process each HRD downlink file to produce a single time-ordered set of Aquarius science blocks and removes duplicates– developed by Joel Gales - ADPS. Level-0-to-1A – separate Level-0 files into orbits, unpack science data, incorporate overlapping ephemeris and SAC-D HKT and convert Aquarius HKT – developed by Joel Gales - ADPS. Telemetry Analysis – HKT data from Level-1A files analyzed for web display on the Aquarius web site – developed by Susie Kennison, Norman Kuring and Liang Hong - ADPS/ACCS. Interactive Telemetry Analysis - HKT files analyze using CONAE-provided telemetry viewer. Level-1A Merge – consolidate Level-1A files from overlapping downlinks into a single, best-quality full orbit product – Joel Gales - ADPS. Level-1A-to-2 – perform calibration, atmospheric correction and salinity retrieval for Aquarius science data – radiometer and scatterometer code delivered by RSS and JPL, respectively; integration and input/output code developed by Joel Gales and Liang Hong - ADPS. Level-2-to-3 Binning – Level-2 salinity retrievals for one day geographically projected and collected into equal-area bins – existing OBPG software modified by Joel Gales- ADPS. Level-2-to-3 Smoothing – Level-2 salinity retrievals for one day optimally interpolated into equal-area bins – algorithm by Jonathan Lilly/ESR implemented by Joel Gales - ADPS. Level-3 Binning and Mapping – Level-3 binned files aggregated to longer time periods (weekly, monthly, etc.) and projected onto map grid – existing OBPG software. All processing steps are run automatically when all input data sets are available. All software exists in at least preliminary prelaunch form at this time. Science Data Processing

  29. Aquarius data product archiving at ADPS will be performed using the existing ODPS archive catalog database and RAID-based data storage system (> 1 PetaByte of current storage for SeaWiFS, MODIS, MERIS, OCTS, CZCS, etc.) Aquarius data distribution during the active life of the mission will be performed using the existing ODPS browse and order system (examples to follow). All source data and “validated” data products will be delivered to the JPL PO.DAAC for permanent archive, value-added services and long-term distribution (next slides). Data Archive and Distribution

  30. PO.DAAC (Physical Oceanography Distributed Active Archive Center) responsibilities: Long-term (Life of Mission and Beyond) data management, distribution & archive of the Aquarius mission data. Ensure data maintenance, usability, access, provenance and security. Ensure integrity of Aquarius data through quality, quantity, continuity and latency audits. Ensure all Aquarius products conform to NASA’s file and metadata standards. Ensure all Aquarius metadata are delivered to the NASA metadata registry (ECHO). Implement and maintain PO.DAAC Aquarius ftp site and web pages. Maintain data Aquarius data access tools including product/granule search, OpenDAP, L2 and L3 subsetters. Develop and maintain Aquarius product user guides and read software. Answer user questions concerning Aquarius data. Configure and implement the PO.DAAC Data Management & Archive System (DMAS) to conform to the interface specification and product ingest requirements. Report data access metrics.

  43. The Aquarius Validation Data System (AVDS) will statistically evaluate the Aquarius SSS data product using a global set of in situ salinity measurements (e.g., Argos buoys) The ADPS will support the validation activity by acquiring the in situ data from AVDS, performing matchups with the Aquarius Level-2 data products, and uploading the matchup files to AVDS. The rationale for the data exchange is to streamline this activity by using preexisting ADPS hardware, software, and satellite data processing facilities, thereby eliminating the redundant effort of developing parallel facilities. A successful data exchange simulation was accomplished using in situ water temperature measurements and the MODIS-Aqua 11-micron SST data product. The AVDS support testing will be included in the mission simulation described under Integration and Testing. Validation Support

  46. Level-1 Requirement: No later than twelve (12) months after the end of the IOC period, the Aquarius Project shall record, process, archive, and deliver the first release of Level 1A and Level 3 data products to a NASA Distributed Active Archive Center (DAAC), Level-1 Requirement: After the first release of Aquarius data, the Aquarius Level 1A and Level 3 data products shall be delivered to the DAAC no later than six months after measurements are taken in orbit. Level-1 Requirement: During the mission life, all products shall be available to the science community from the Aquarius Data Processing Segment (ADPS) and the final data products produced by the Aquarius Project shall be delivered to the DAAC within six (6) months after the end of the prime mission Periodic Reprocessing

  47. Development and test environments allow for multiple algorithm versions to be run on the entire mission data set to test the impacts of calibration and algorithm improvements. The results of these “reprocessings” are made immediately available to the science team members via web and ftp mechanisms Using SeaWiFS as a benchmark, the most recent reprocessing of the entire mission-long (ten year) data set required 10 hours or 1 year/hour. Aquarius is ½ the data volume of SeaWiFS so data storage and system throughput are NOT a concern. A better estimate of the actual processing throughput will be derived once we process the year-long Aquarius simulated data set later this month Once the calibration/algorithm changes have been validated and approved by the Science Team, a mission-long reprocessing will be initiated and the new products and documentation will be made available to the science community and PO.DAAC.
