The official NASA/Aquarius end-of-mission V5.0 dataset is available from the PO.DAAC.  The series spans the complete 3-year, 9-month period of Aquarius science data availability, from August 25, 2011 through June 7, 2015. Data sets comprising this v5.0 release include the Level 2 orbital data and Level 3 mapped salinity, wind speed, and derived density and spiciness products at 1 degree spatial resolution for ascending, descending and combined passes and for the following time intervals: daily, 7 day, monthly, seasonal, annual.  Seasonal and monthly climatology, cumulative (mission mean), and 7-day and 28-day running mean products are also included.  A complementary set of similarly gridded L3 ancillary SST products are also provided.

The Aquarius V5.0 data sets are described and discoverable via the PO.DAAC data portal.   Access to these data is via PO.DAAC’s public FTP site: .  The data are also accessible via a range of PO.DAAC tools and services: OPeNDAP, THREDDS, Aquarius Level 3 Browser, LAS, the HiTIDE L2 subsetter and associated Web Services.

The Aquarius Data Users Guide, Aquarius Data Validation Document, and other primary technical documentation , are available from the FTP site together with reader software.   General information regarding Aquarius/SAC-D mission is available from the mission website and also via PO.DAAC’s Aquarius  and salinity webpages.
