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), as part
of 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 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 NCEI archive system to create an
archival information package (an NCEI 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 NCEI archive file system.

The file about/GDS2-L4-BLACKSEA-GOS-OISST_HR-v2.0-2020-138.xml is based on
the descriptive information provided by the GDAC granule search service.
