Source: An error in the ingest processing of the files in this data set
resulted in these files being stored in a directory which omitted the
version number of the data set. This update moves the files into the
correctly versioned directory. No other changes were made to this accession.

Updates received on:           2015-05-19

Actions: Updates were received for this data set.  These updates were copied
into the data/0-data directory of this accession.  These updates may provide
additional files or replace obsolete files.  However, all of the files
received prior to this update are available in the preceding version of this
accession.

The directory GDS2-L2P-VIIRS_NPP-OSPO was renamed to GDS2-L2P-VIIRS_NPP-OSPO-v2.3.

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: 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, 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
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-v2.3-2015-138.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).
