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.
