Heliophysics is a relatively new domain that explores the
Sun-Solar System Connection;
it requires the joint exploitation of solar, heliospheric and planetary magnetospheric and ionospheric observations.
The Heliophysics Integrated Observatory, HELIO, is a Research Infrastructure that
address the needs of a broad community of researchers in heliophysics;
it has deployed a distributed network of services that
provides the most comprehensive integrated information system in this domain.
HELIO provides access to data
from more than 200 instruments from observatories throughout the heliosphere
and the tools to make intelligent choices about which are of interest.
The Event Catalogue contains lists
describing solar flares, CMEs, energetic particles and phenomena in the solar wind;
the Feature Catalogue describes the evolution of solar and heliospheric features;
the Instrument Capability and Location services
provide information about which instruments are suitably located
and a propagation model helps to tie the observations together.
The services can be accessed through
a very capable GUI, or orchestrated using Workflow or scripting capabilities.
HELIO is a key component of a worldwide effort to integrate heliophysics data and has
coordinate closely with international organisations to exploit synergies with complementary domains.
The project was funded under the Capacities Specific Programme
within the EC's Seventh Framework Programme (FP7).
