The Physical Oceanography Distributed Active Archive Center (PO.DAAC) is
pleased to announce the availability of the Level-2 product from the Combined
Active-Passive (CAP) Algorithm applied to the Aquarius/SAC-D version 2.0
data. The CAP algorithm simultaneously retrieves salinity, wind speed
and wind direction by minimizing the sum of squared differences between model
and observations. After testing the CAP algorithm against the Aquarius data,
the least squares algorithm (LSE) performs very well for the Aquarius version
2.0 data. Data are processed through the end of February and will be
augmented on monthly intervals for the next few months. The lag is due
to the delays required to have the new data necessary to
recalculate the Aquarius sensor calibrations. All users are strongly
encouraged to work with V2.0 over any previous Aquarius/CAP evaluation
versions.
The Aquarius v2.0 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://podaac.jpl.nasa.gov/allData/aquarius/L2/CAPv2/
) and also OPeNDAP.
The CAP Users Guide and other primary technical documentation
relating to Aquarius data, 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.
