Existing projects
• GODIVA (NERC pilot project)
– Grid for oceanographers to enable distributed analysis
and visualisation of ocean data
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
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
Example workflow
•
First Web Service
(GADS) extracts data
from a server
(from myGrid project)
INPUTS
• Second Web Service
finds the depth of an
isotherm in the dataset

• 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
Real-time data
access
• Met Office
FOAM data
• Can easily create
subsets of data
Intercomparison of model
data
Compare results
of different ocean
models
e.g. EU MERSEA
project
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)
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
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
Future projects

•

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
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
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
