Source: These data were submitted for archive to NCEI from the Physical
Oceanography Distributed Active Archive Center (PO.DAAC), Jet Propulsion
Laboratory (JPL), NASA/California Institute of Technology (Caltech), in
their role as a Data Archiving Centre (DAC) for the Group for High
Resolution Sea Surface Temperature (GHRSST) program.

Actions: GHRSST data are received daily by NCEI 30 days after observation
(prior to 30 days they are available through the DAC 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 NASA data service and uses MD5 hash digests to verify the
transmission of the data. Corresponding metadata are downloaded from a
NASA 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 NCEI archive system
to create an archival information package (an NCEI accession). On a routine
basis, an HTTP/FTP/TDS dissemination hierarchy is then constructed pointing
to the data and metadata residing in the formal NCEI archive file system.

Files:

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

data/0-data/
This directory contains the data files as submitted to NCEI.

The file naming convention for the GHRSST GDS 2.0 is described in GDS 2.0
Technical Specifications: GDS_TechSpecs_v2.0.pdf (GHRSST documentation, NCEI
Accession 0123222).
