Observing System Monitoring Center (OSMC)Status
Update

• Office of Climate Observation
• May 2006
• Kevin OBrien
• Steve Hankin PMEL (co-PI)
• Kevin Kern NDBC (co-PI)
• Ted Habermann NGDC (co-PI)

2
to provide a system view of global ocean
climate observations

A partnership

• PMELUser interface logic tools
• NDBCData assembly operations
• NGDC
• Database GIS consulting

OSMC (meta)database

• What is the climate data record?
• Current (meta)data (realtime)
• GTS -- primary source
• Historical (meta)data
• poorly integrated
• need DMAC integration
• for now use a GTS archive(misses e.g. NOAA
  research cruises)

5
OSMC (meta)database at NDBC

• Met and Ocean surface data are updated daily with
  GODAE T-files (06, 12, 18, 24) from the
  previous day350 MB of data per day
• URLhttp//usgodae2.fnmoc.navy.mil/ftp/outgoing/fn
  moc/data/met/2005031706.tar.Z
• 1x1 degree gridded metadata netCDF summary files
  are updated daily
• The database repository begins 1 June 2004

6
OSMC (meta)database at NDBC

• Drifter updates from JCOMMOPS
• URL ftp//ftp.jcommops.org/Argo/Status/status.t
  xt
• Profiling float data from US GODAE Server
• Profile repository starts 1 January 2004
• Country information is assigned based on WMO
  allocation table
• URL http//www.wmo.ch/web/aom/marprog/Operation
  al-Information/buoy-ids.htm

Country - is based on ISO 3166, which defines
unique 2-character identifiers for each country.
OSMC RDBMS Entity Diagram





Organization - identifies an agency, institute,
university, or private company that owns or
operates a reporting platform
Datasource - identifies the source of the data.


Platform - identifies a ship, drifting buoy,
moored buoy station, or other platform that
reports marine data.
Observation - records the instance of a marine
observation for a reporting date and time.
Obs_Delay - used to retain ship observation to
enforce the 48 hour delay.

OSMC IT Environment

• Hosted at NDBC
• Dell PowerEdge 2650
• Dual Processor 3.06 GHz/1MB Cache
• Five 146 GB Harddrive
• Red Hat Enterprise Linux AS 4.0
• Oracle Database

10
Who are the users?

• Office of Climate Observation
• NOAA Observing system managers
• Scientific Community

11
Tools OSMC should provide

• Overview (where are the obs?)
• Drill-down (what are the obs?)
• Evaluation (are the obs adequate?)

27
Visualization evaluation
Number of platforms per 5x5 degree box reporting
SST this month
28
Visualization evaluation
5x5 degree boxes this month that had one or more
SST obs every day

The OSMC doesnt look like a Live Access Server
but it is (Shown is the more traditional LAS
user interface)
30
Adopt-a-Drifter
is another specialized user interface to the same
OSMC server
31
Can the database keep up?

• Database performance evaluation
• Performance has increased by orders of magnitude
• Ever-increasing complexity of useful queries
• Need for spatially-based queries
• Can metrics be efficiently calculated directly
  from database?

32
A new view of the OSMC database
33
Providing an overview of OSMC

• Developing summary OSMC data table views
• Number of daily observations
• by platform
• by country, platform, and date, with drop-down
  country select
• As a demonstration of spatial query capabilities
• of platforms in Exclusive Economic Zones or
  ocean and sea polygons
• Including drill down to observations

Whats ahead

• Security
• Delay ship observations by 48 hours
• Performance
• Support time-partitioning of database
• Create daily summary tables
• Metrics
• User feedback
• Continue work with OCO on UI tools

40
Whats ahead

• Accountability
• Continue adding variables
• Tease apart platforms better
• Reduce unidentified/unknown platforms
• Integration
• With climate products
• With ocean/climate modeling efforts
• Into IOOS GEOSS framework

41
How Can You Help?

• Types of metrics needed
• Useful tools
• Other platforms/datasets/variables, etc
• OSMC will be available through
• http//www.oco.noaa.gov
