OSMC: a “science manager’s view” of theglobal ocean climate observing system


Cross-NOAA partners …• OCO

• PMEL

• NDBC

• NGDC

• IOOS (NEW)

(Funding & direction)

(User interface logic & tools)

(Data assembly & operations)

(Database & GIS consulting)

(Coastal Observations)


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

Evaluation


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


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”)


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.)


Strategies for integrationwith GOSUD and SAMOS:

1. Metadata– (Push) Put SAMOS/GOSUD obs onto the GTS (OSMC already receives GTS)

– (Pull) (see next slide)


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


Underway ocean carbon obs with LAS - analogous data management project

• Observationsstored in adatabase(mySQL)

Easily integratedwith the OSMC


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?


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?


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

OSMC LAS

By the way …

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

(Shown is thetraditional LASuser interface)


Integration ofobservationswith modelsand satellitesvia NVODS,and IOOS


• 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:
