***************************************************************** Journal for accession number: 0156055 Created on: 2016-07-26 03:27:40 UTC By: Automated Ingest Agent 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-L2P-IASI_SST_METOP_B-OSISAF-v1-2016-114.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 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, NODC Accession 0123222).
