Source: These data were submitted for archive to the NODC from the Physical
Oceanography Distributed Active Archive Center (PO.DAAC), Jet Propulsion
Laboratory (JPL), NASA/California Institute of Technology (Caltech), as part
of the Group for High Resolution Sea Surface Temperature (GHRSST) program.

Actions: GHRSST data is received daily by the NODC 30 days after observation
(prior to 30 days it is available through the GDAC interface) through an
automated procedure made possible largely by the formalized procedures
developed within the GHRSST, especially those pertaining to data management,
metadata, and file naming conventions. An automated process downloads data
each day from the PO.DAAC FTP server and uses MD5 hash digests to verify the
transmission of the data.  Corresponding metadata are downloaded from a web
service in XML format.  An automated process uses a combination of boilerplate
information, information from the filenames, information from the metadata
records, and information generated by the NODC archive system to create an
archival information package (an NODC accession).  On a routine basis, an
HTTP/FTP/OPeNDAP/TDS dissemination hierarchy is then constructed pointing to
the data and metadata residing in the formal NODC archive file system.

The file about/GDS2-L2P-AVHRRMTB_G-NAVO-v1-2014-214.xml is based on the
descriptive information provided by the GDAC granule search service.

Files:

about/ 
This directory contains files created by NODC staff, including 'negotiable'
information between NODC staff and the data provider.

data/0-data/
This directory contains files in their original format as downloaded to NODC.

The file naming convention for the GHRSST GDS 2.0 is described in GDS 2.0

Accession 0123222).
