| Zusammenfassung |
| Space physics models with good predictive capabilities may be used to forecast
accurately the state of the near-Earth space environment and to enable end user
communities to mitigate the effects of adverse space weather on humans and technological
systems. The results obtained from model runs, and also the validation of their
performance accuracy, depend to a large extent on the availability of data from as many as
possible regions of the near-Earth geospace. Despite the abundance and variety
of related observational data, their exploitation is still challenging as they come
from different sensors, in different formats and time resolution, and are provided
from various organizations worldwide with different distribution procedures and
policies.
The primary objective of ESPAS is to provide the e-Infrastructure necessary to support
the access to observations, extending from the Earth’s atmosphere up to the outer radiation
belts, including ionosondes, incoherent scatter radars, magnetometers, GNSS receivers and a
large number of space sensors and radars. The development of the ESPAS common interface
will allow users to uniformly find, access, and use resources of near-Earth space environment
observations from ground-based and space-borne instruments and data from distributed data
repositories, based on semantically web services (www.espas-fp7.eu). The first phase that
will lead to the release of a first prototype includes the design and development of
the data model that will support location of all available data from ground based
experiments and satellite missions, available at certain spatial coordinates and time
interval. For the first release only the basic data sources will be registered (i.e. Cluster,
IMAGE/RPI, DEMETER, DIAS, EISCAT ISRs and SWACI). In a second phase, when all
databases and enhanced databases will be registered, the ESPAS infrastructure must be
extensively tested through the application of several use cases, designed to serve
the needs of the wide interdisciplinary users and producers communities, such as
the ionospheric, thermospheric, magnetospheric, space weather and space climate
communities, the geophysics community, the space communications engineering, HF
users, satellite operators, navigation and surveillance systems, and space agencies. |
