Aquarius Data Processing FlowThe Level-0 and 1A processing algorithms and software are developed entirely by the OBPG.The Level-1B and 2 algorithms and science code are developed by the Aquarius Science Team;the code is delivered to the OBPG, who are responsible for the implementation of the operationalsoftware, including data product input/output and quality flags. The Level-3 binning software isadapted from the existing Ocean product software. The Level-3 smoothing algorithms wereprovided by the Science Team and implemented in software by the OBPG.The ancillary data requirements for Aquarius are also unique. The requirements for the Aquariusancillary data types and sources are given in Reference 2. This information is summarized inTable 3-2.Data DistributionThe products will be distributed through the ODPS web-based browse and distribution system.The products will also be delivered to the Physical Oceanography DAAC (PO.DAAC) at JPL, asdescribed in Reference 3. In accordance with the Aquarius Level-3 Requirements, the initialproduct delivery will be made no later than 12 months after launch, and all subsequent deliverieswithin 6 months of data acquisition. The method of delivery will be for the PO.DAAC toacquire the products from the ODPS distribution site.
