The Home Page of the GHRSST Data Assembly and Systems Technical Advisory Group (DAS-TAG)
The GHRSST Data Assembly and Systems TAG is responsible for the day-to-day operational specifiaction and management of GHRSST data products and services. In paractice, this involves the specification and control of all aspects of data archive, dissemination, file level and discovery metadata, international standards conformance, quality control and assurace issues, product content, amongst many others. The DAS-TAG is a dynamic team drawing on the collective resources of an international membership that is actively involved in satellite and in situ data management issues.
This group is responsible for overseeing technical issues involving the data management activities of the GHRSST project.this includes:
- Data Assembly
- XML
- Data management systems
- The GHRSST Data Processing Specification (GDS)
Current membership includes:
- Andy Bingham (Chair), Jet Propulsion Laboratory/California Institute of Technology, GDAC, Global Data Assembly Center
- Ed Armstrong Jet Propulsion Laboratory/California Institute of Technology, GDAC, Global Data Assembly Center
- Chelle Gentemann: Remote Sensing Systems, Santa Rosa California
- Ken Casey: National Oceanographic Data Center/National Oceanographic and Atmospheric Administration (NODC/NOAA), LTRSF Long Term Reanalysis and Stewardship Facility.
- Jorge Vazquez: Jet Propulsion Laboratory/California Institute of Technology, GDAC, Global Data Assembly Center
- Ian Barton: Bluelink, Australia
- Jean-Francois Piolle: Medspiration, France
- Craig Donlon: International Chair of GHRSST-PP project
The DAS-TAG has defined technical issues for both the distribution and long-term archive of the GHRSST data. The Long Term Stewardship and Reanalysis Facility (NOAA/NODC NODC/LTSRF) will be responsible for the permanent archive of all GHRSST data. The GDAC, located at the Physical Oceanography Distributed Active Archive Center (PODAAC), will be responsible for maintaining the real time distribution of the GHRSST data. Additionally the GDAC is tasked with maintaining the GHRSST master metadata repository (MMR), the matchup databases (MDB), and providing missing ancillary fields in the L2P format data files.
The DAS-TAG has defined the FTP structure for both the GDAC and the LTRSF at NODC. The LTRSF is tasked with both the long-term archive of all GHRSST data and the reanalysis of the GHRSST-PP data. The basic layout can be found in the DAS-TAG termns of reference document.
