Grid for Ocean Diagnostics, Interactive
Visualisation and Analysis (GODIVA)

Web Services

• Powerful way to implement distributed computing
  modular, loosely-coupled
• Platform neutral
• Message passing in machine-independent form
• Existing code can be easily converted to WS form
• Client can be desktop, handheld PC, mobile phone,
  another Web Service, etc
• Future Grid Services
• Extend WS to add features to help Grid computing

Web and Grid servicesfor large model data sets

• (Data discovery) NERC DataGrid
• Distributed Data Management Layer (GADS)
• Data Delivery Service (http, ftp, gridftp,
  security)
• Visualisation Services (Server side, distributed,
  client side)
• Data Transformation services (interpolation,
  re-mapping)
• Diagnostics and intercomparison services (Grid
  Services)

Data sets currently served

• Met Office real time ocean forecasts at 1, 1/9
  resolution
• ECMWF surface Met conditions (10 day forecasts)
• High Resolution ocean model data (1/12 OCCAM)
• Some satellite data e.g. TRMM (provided by SOC)

The Future

• Reading e-Science Centre (ReSC)
• Promote Web and Grid Service technology across
  environmental science community Open Source
• Academic community (Data Assimilation Research
  Centre)
• Met Office, Environment Agency
• ECMWF and EU Framework e.g. MERSEA
• Commercial sector (SEEDA project, BMT and
  Maritime Coastguard Agency for Oil spill, Search
  and Rescue)
• Further collaborations and inter-operability with
  other environmental science Grids

Conclusions

• Developing techniques and tools for working with
  very large data sets
• Of general use, not just for oceanographers
• Web Services are very important
• Enables collaboration across institutions and
  national borders
• Applications to both public and commercial sectors
