The PO.DAAC is pleased to announce the availability of the version 5.0 Aquarius/SAC-D data. This is the official NASA/Aquarius Project end-of-mission dataset spanning the complete 3-year, 9-month period of Aquarius science data availability, from August 25, 2011 through June 7, 2015. Likely future reprocessing releases of the Aquarius data will occur when further measurable algorithm improvements are achieved.
Data sets comprising this v5.0 release include the Level 2 orbital data and Level 3 mapped salinity, rain-flagged 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. Additionally, a complementary set of similarly gridded L3 ancillary SST products are provided. A summary of improvements with this new version of the Aquarius data is available here. All users are advised to work with V5.0 over any previous versions.
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: ftp://podaac-ftp.jpl.nasa.gov/allData/aquarius/ . 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.
