Summary

• What did we get through the use of Unidata
  technology?
• Standards-based delivery of aggregated model data
  with minimal burden on the data provider
• Single point of access for regional model results
• Model data interoperability via standard software
• Multiple modes of access for users
• More eyes on the model results
• More usage of model results
• Faster feedback to modelers
• Improved models!
• We now have an IOOS THREDDS Catalog that points
  to 17 THREDDS servers running in all 11 IOOS
  Regions
• So are we done? Well.

Unidata and Oceanography in the Future

• Develop support for unstructured grids Need a
  new Scientific Feature type in the CDM, new class
  and methods in NetCDF-Java, delivery via WMS in
  TDS, and visualization in IDV.
• Develop protocols and back end software in the
  TDS to allow server side functions such as
  subsetting and averaging functions.
• Strengthen ties between Unidata, the Integrated
  Ocean Observing System (IOOS), and the
  NSF-sponsored Ocean Observing Initiative
  CyberInfrastructure (OOI-CI) project. I hope to
  play a role here

• Matthew Arrott speaking at the Ocean Observing
  Initiative CyberInfrastructure kick-off meeting
  one month ago. This is a 40 million dollar, 5
  year project, and there were approximately 100
  people in the room)
• "Let me explain why Unidata is here. Everytime I
  go out in the field and look at the tools that
  scientists are using, they are using Unidata's
  tools. It is our view that how you get to the CI
  will be through Unidata's tools. This is why you
  see us speak more about infrastructure than about
  application. We are not developing applications
  that in conflict with the existing practices of
  scientists. We are there to accelerate their
  practices, to expand their practices. The best
  way to do that is to deploy into the existing
  operational context and Unidata represents one of
  the strongest institutions in the country in
  terms of supplying applications to the end users."
