The OSMC science manager needs:
• Visualize (where are/were the obs?)
• Drill-down (who/what made the obs?)
• Evaluation (are/were the obs adequate?)
• Promote community-wide data integration

Community data integration• Scientists can get the data
– as a table, netCDF (CF) file– as a file– as a link to a Web Service
• OPeNDAP• OGC protocols (NOAA IOOS “DIF” standards)
• Data “live” from the authoritativesource
• OSMC is “just another user” of integration
-
June 2008 2nd Joint GOSUD/SAMOS Workshop
The OSMC (meta)database … the “climate data record”
How do we monitor it?
• 1st guess: GTS (not really the climate data record)
• Climate data management programs– e.g. SAMOS & GOSUD– need integration strategies (“DMAC”)
-
June 2008 2nd Joint GOSUD/SAMOS Workshop
Getting metadata and datainto the OSMC framework
Two types of access …
1. ‘platform footprints’ shown on maps metadata ingested into OSMC (data “push”)
2. scientific plots and tables direct access to data (data “pull”)(Preferably authoritative data directly from climate data partners.)
-
June 2008 2nd Joint GOSUD/SAMOS Workshop
Strategies for integrationwith GOSUD and SAMOS:
1. Metadata– (Push) Put SAMOS/GOSUD obs onto the GTS (OSMC already receives GTS)
– (Pull) (see next slide)
-
June 2008 2nd Joint GOSUD/SAMOS Workshop
Strategies for integration:
2. Direct access to data (Pull)OSMC makes queries to SAMOS/GOSUD using…
– for databases: SQL/JDBC
– for netCDF file collections: OPeNDAP andTHREDDS
– Web Services• DAPPER (established OPeNDAP conventions)• SOS (OGC solutions under development in IOOS)
– for Live Access Server sites (e.g. ocean carbon)• LAS protocol

June 2008 2nd Joint GOSUD/SAMOS Workshop
Summary:(“pitch for collaboration”)
Access to SAMOS and GOSUD metadata & data
1. Metadata (for cruise footprints) (simplest) SAMOS/GOSUD obs on GTS
2. Direct data access (for tables, graphics, segue) LAS, JDBC, or OPeNDAP access
1. What would the OSMC project like?
-
June 2008 2nd Joint GOSUD/SAMOS Workshop
Summary:
Depends on the strategy and data system…OSMC would actively assist:
• Putting data onto GTS• Installing/configuring LAS or OPeNDAP• Using remote access wherever possible
2. How much effort would this be?
-
June 2008 2nd Joint GOSUD/SAMOS Workshop
Summary:
• Be more fully included in NOAA observing systemassessments– visibility encourages scientific and QC feedback (and makes
program managers happy )– a partnership towards a “Climate Service”
• New ways to deliver data to your users
The “right thing to do”Data integration is a community goal.By each sharing one data source everyone gets access to many.
3. How would it benefit GODUS/SAMOS?
Note: use of netCDF formats built upon “CF” would be desirable

By the way …
the OSMCdoesn’t looklike a LiveAccessServer,but it is.

• Queries directly to SAMOS/GOSUD database (SQL, JDBC)
• OPeNDAP and THREDDS (if netCDF filecollections)
• Web Services– DAPPER (established OPeNDAP conventions)– SOS (exploratory OGC solution)– LAS “REST” protocol
(re-use integration strategy from carbon data)
Several strategies forintegration:
