  1. Reading University’s Environmental Systems Science Centre ESSC Technical Director Jon Blower ESSC Director Keith Haines ESSC Director Rachel Harrison CS Meteorology Dept. Centre Global Atm. Modelling Data Assimilation Res. Centre Met Office Units Plant Sciences Dept. Reading e-Science Centre e-Science for a digitised environment Environmental Science Applications Analysis, modelling and assimilation of climate and real-time data External Collaborations Associated Personnel

  2. Existing projects • GODIVA (NERC pilot project) • Grid for oceanographers to enable distributed analysis and visualisation of ocean data

  3. GODIVA Web Portal (http://www.nerc-essc.ac.uk/godiva) • Allows users to interactively select data for download using a GUI • Users can create movies on the fly • cf. Live Access Server • Useful as browse tool

  4. Existing projects • GODIVA (NERC pilot project) • Grid for oceanographers to enable distributed analysis and visualisation of ocean data • GADS (Grid Access Data Service) • Web Service for providing access to data (~1 TB at ESSC alone) • Will be part of workflows (e.g. for use in GODIVA) • Workflows are groups of Web Services which work together to form a distributed application

  5. Example workflow (from myGrid project) • First Web Service (GADS) extracts data from a server • Second Web Service finds the depth of an isotherm in the dataset INPUTS OUTPUT

  6. Existing projects • GODIVA (NERC pilot project) • Grid for oceanographers to enable distributed analysis and visualisation of ocean data • GADS (Grid Access Data Service) • Web Service for providing access to data • Will be part of workflows (for use in GODIVA) • Provision of live Met Office data to community • Thousands of users, hundreds of institutions, tens of countries • Esp. for MERSEA (EU model intercomparison project) • Also in future to BMT for oil spill / search and rescue systems

  7. Real-time data access • Met Office FOAM data • Can easily create subsets of data

  8. Intercomparison of model data Compare results of different ocean models e.g. EU MERSEA project

  9. Existing projects (contd.) • TRACK software for identifying weather systems • Computationally intensive but parallel, best run on a distributed system • Would like to do this on many different data sets (e.g. ECMWF)

  10. Future projects • Create more Web Services for benefit of community • Collate Web Services written by other people (create UDDI registry) • Use satellite / in situ data in addition to model data • SEEDA • Provision of Met Office data to BMT

  11. SEEDA project • Create prototype of system in which real-time Met Office data are used to predict path of oil spills This is the OSIS software, which currently uses tidal data only: would be improved with real-time Met Office forecasts of ocean currents

  12. Future projects • Create more Web Services for benefit of community • Collate Web Services written by other people • Use satellite / in situ data in addition to model data • SEEDA • Provision of Met Office data to BMT • EurOPA • European portal for real-time data for marine hazard analysis (EU) • POPPIE • Environment Agency / Met Office pollution tracking software • Re-engineer software to improve architecture: use Web Services • Bristol University: simulations of fragmentation in volcanic rocks • Monte Carlo simulations of “virtual” rocks

  13. Technical expertise • Strong focus on Web Services • Data access • Data analysis/processing • Data visualisation • Creating distributed applications using workflow engines to orchestrate Web Services • Also web portals (cf. Live Access Server) – ESP community • Future migration to Grid Services: would like help with OGSA! • Question: How to transfer large data sets between Web Services? • Use of Condor pool at ESSC

  14. Summary • ReSC is engaging with environmental scientists in many disciplines and sectors • Focus on atmosphere/ocean science • Working with universities, govt agencies and commercial sector • Would like to draw on experience of other e-scientists • ReSC complements, but is distinct from, NIEeS
