Overview
e-Science / NERC Datagrid
Oceans & Atmospheres data
Solid Earth and Environment community
HPC services for simulation & inversion
Standards-based loosely-coupled data services
SEE Grid
Cox/2005 AGU Spring
NERC DataGrid - data transfer

Focus on large datasets, simple structures
Time-series, profiles, gridded datasets
Series and collections

One service – many uses
GML-based data can be …. Rendered into a
queryable map …
… formatted into a
report or ….
… read and used by any
WFS/GML enabled application

Fields vs. objects
classic geology“Feature” viewpoint
classic geophysics“Coverage” viewpoint
• simple data structures• collated/gridded
ready for analysisnetCDF, HDF-EOS
• complex data • database insertion• complete feature interpretations XML documents

Key Points
e-Science depends on
Informational Services – to supply modelling constraints
Computational Services – to supply simulators and solvers
e-Science community focus on “Grid” services
high-performance computing, PDE solvers – remote but tight connections
large datasets, data warehouses – simple data structures
Geospatial community working on REST web-services
loosely-coupled, decision-support– on-demand discovery, binding and chaining,
detailed semantics – complex data-structures, community schemas
