Aquarius Data Processing System Overview
• The Aquarius Ground System at NASA/GSFC consists of the Aquarius Data Processing System (ADPS) and the Aquarius Command and Control System.
• The ADPS will support: – Acquisition and ingest of Aquarius/SAC-D data from CONAE. – Acquisition of dynamic ancillary required to support the science processing. – Processing of Aquarius data to standard product levels using algorithms provided
by the Science Team. – Quality control of data products using methods specified by the Science Team. – Match-up of Aquarius data with in situ salinity measurements. – Archive and distribution of all data products during the active life of the mission to
the science team and general science community. – Delivery of source data (Level-1a) and “validated” Level-2 and Level-3 derived
data products to the PO.DAAC.
• The ADPS will be supported within the existing infrastructure of the Ocean Biology Processing Group (OBPG).

Science Data Processing 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.

• Radiometer and Scatterometer 2009 code deliveries have been integrated and installed in the data processing system.
• Latest versions of Level-1A and Level-3 software have been installed. • Ancillary data to support processing have been acquired and ingested. • The one-year (2007) simulated data set has been processed to Level-1A,
Level-2 and Level-3 products: – http://oceancolor.gsfc.nasa.gov/cgi/aquarius (Level1A/2 browser) – http://oceancolor.gsfc.nasa.gov/cgi/l3 (Level-3 browser) – http://oceandata.sci.gsfc.nasa.gov/Aquarius (FTP-like interface)
• The PO.DAAC is downloading the simulated data products and making them available (see poster by Gregg Foti).
• AVDS processing is in progress with the 2007 data set.
Science Code Status

ADPS and Data Distribution Aquarius/SAC-D Science Team Meeting
• From now until launch we need to:
– Integrate Radiometer and Scatterometer code updates into data processing system.
– Incorporate additional quality flags into software and products. – Develop ingest procedures for additional ancillary data required by
new code. – Incorporate SAC-D HKT format into Level-1A processing. – Verify output products with Science Team. – Begin real-time mission simulation (August 2010 --> Launch). – Incorporate additional prelaunch updates into the science software
(as needed). – Participate in mission tests as scheduled.

• Data • On-site
• Downlinks, L0, L1a data files • primary copy on RAID6 storage node • mirror copy on separate RAID6 storage node, at file creation
• Science Products • primary copy on RAID6 storage node • mirror copy if desired, or regenerated from L1a
• Off-site • Downlinks: stored at CONAE • L1A archived at PO.DAAC
• Source Code • On-site
• primary copy on subversion server, RAID6 • mirror copy on backup Subversion server, RAID6, nightly mirror
• Off-site • Subversion data copied to external disk, taken off-site every 1 month • Multiple copies, given to Project Manager, SE, Processing Manager
