Source: These data were submitted for archive to NCEI from the US DOC; NOAA;
NESDIS; Office of Satellite and Product Operations, as part of the Group for
High Resolution Sea Surface Temperature (GHRSST) program.

Actions: While most GHRSST data are retrieved from the PO.DAAC 30 days after
observation, these GHRSST data are received daily by NCEI, as soon as they
become available on the NDE Distribution Server, 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 NDE Distribution Server and uses MD5 hash digests to verify
the transmission of the data. Corresponding metadata are downloaded from a
PO.DAAC web service in XML format, if available. 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 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-L2P-VIIRS_NPP-OSPO-v2.4-2016-208.xml is based on the
descriptive information provided by the GDAC granule search service.

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 files in their original format as downloaded 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, NODC
Accession 0123222).
