The PO.DAAC is pleased to announce the availability of the version 4.0
Aquarius/SAC-D data. This is the official NASA/Aquarius Project
end-of-prime-mission dataset spanning the complete 3 year, 9 nine month
period of Aquarius science data availability, from August 25, 2011 through
June 7, 2015 when an unrecoverable hardware failure caused the end of the
mission. This end-of-prime mission dataset does not preclude future
reprocessings. An updated version (V5.0) is planned for release in
2016, and subsequent updates will be released when measurable improvements
are achieved.
Data sets comprising this release include the Level 2 orbital data and Level
3 mapped salinity, wind speed, and derived density products at 1 degree
spatial resolution for ascending, descending and combined passes and for the
following time intervals: daily, 7 day, monthly, seasonal, annual. New
products (added since V3.0), in addition to density, include 7-day
and 28-day running mean products, seasonal and monthly climatology datasets,
and cumulative (mission mean) products. The V4.0 data are also comprised of a
complementary set of similarly gridded L3 ancillary SST products. A summary
of improvements with this new version of the Aquarius data is
available here.
All users are advised to work with v4.0 over any previous versions.
The Aquarius v4.0 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.
