  1. IQuOD Data Flow Tim Boyer NODC

  2. Inflow How will IQuOD quality controlled data get into the World Ocean Database?

  3. NODC Information Stream Not Always Publicly Accessible NODC Permanent Archive [non-uniform Format] Delayed Mode Data World Ocean Database Additional QC Uniform format Data quality information Near Real-Time Availability GTSPP Argo/GODAE Buoys PMEL/JAM

  4. IQuODInformation Stream IQuOD Manual QC Expert Center World Ocean Database IQuOD Automatic QC Uniform format IQuOD Manual QC NODC Permanent Archive Specific IQuOD subset Data quality information

  6. Outflow How will IQuOD quality controlled data get out to users?

  7. INSIDE THE DATA World Ocean Database Internal Storage Generated on the fly Original Profile Data QC Flags (IQuOD) QC Flags (orig) Altered Profile Data (if necessary) QC Flags (WOD) QC Flags (2nd)

  8. Data Dissemination: Yearly by instrument Geographically by instrument WODselect All updated quarterly Format: Native WOD format (compact ASCII) with conversion routines netCDF -> feeds into NODC Geoportal/THREDDS server Working now on subset dissemination through Geoportal

  9. WODselect download page • For ASCII format, choice of two flags: default is originators flag + WOD flag. • For netCDF format, no restriction on number, form of flags • Can also bundle entire IQuODQC’ed dataset. • First, only temperature flags (include WOD flags for other variables?) • Not all data IQuODQC’ed (include automatic IQuoD flags for other temperature data?)

  10. Confluence How will IQuOD quality controlled data be combined with other high value data sources?

  11. NODC to Public Information Stream (Profile Data) Public Access NODC Permanent Archive Geoportal/THREDDS WODselect World Ocean Database Additional QC Uniform format

  12. Ideal NODC to Public Information Stream (Profile Data) NODC Permanent Archive Public Access Geoportal/THREDDS WOD GTSPP Argo PMEL buoys

  13. Ideal NODC to Public Information Stream (in situ Data) NODC Permanent Archive Public Access Geoportal/THREDDS Coastal Buoy Profile Current Thermo salinograph

  14. Best Copy Get Data Information World Ocean Database Get Data Information GTSPP Get Data Information Argo Get Data Information Individual Accessions See all Information Consolidated Granule Level GeoPortal

  15. Best Copy: Get Data • Virtual download through THREDDS Server • tar ball of all data files • CF compliant netCDF format • Files are not uniform in format • Quality control not uniform in execution or as represented by flags

  16. Best Copy Information Description of data which matches request X casts from GTSPP (ocean profile data from 1990 to present Y casts from World Ocean Database (historical ocean profile data from 1772-[WOD most current date] : takes precedence over GTSPP Z cycles from Argo (takes precedence over all others for profiling floats) A daily means from PMEL/NDBC tropical moored buoy arrays (takes precedence over all others for tropical moored buoys) B cruise thermosalinograph records C coastal moored buoy stations
