The Physical Oceanography Distributed Active Archive Center (PO.DAAC) would
like to announce a reprocessing of the Level-3 Combined Active-Passive (CAP)
Aquarius version 2.0 data products. Access to the updated L3 CAP data
is via PO.DAAC’s public FTP site (ftp://podaac-ftp.jpl.nasa.gov/allData/aquarius/L3/mapped/CAPv2/)
and also via OPeNDAP,
and THREDDS.
L3 CAP data visualization and subsetting is available via LAS. The updated version includes
fixing an issue with the truncation of the Gaussian Weighting used in the
Level 2 to Level 3 gridding. Additionally, Aquarius data files that may have
been affected by anomalous spacecraft attitudes were removed from gridding.
For validation purposes the updated Gaussian Weighting version was compared
against the drop-in-the-bucket gridding scheme to verify that the anomalous
biases have been removed.
The v2.0 CAP L3 data sets are described and discoverable via the PO.DAAC data
portal. The CAP Users
Guide, README.CAP and other primary
technical documentation relating to Aquarius data, are available
from the FTP site together with reader software.
