Describe the scientific/technical community and the scientific/technical activity using (planning to use) the EGEE infrastructure. A high-level description is needed (neither a detailed specialist report nor a list of references).
Earth Science (ES) is an all-embracing term for sciences related to the planet Earth, covering a large and diverse user community. Since several years the applications need more and more to have access to different large and heterogenous sets of data, in general via web portals, and to intensive computing facilities.
DEGREE is a consortium of ES partners aiming at promoting the uptake of Grid technology in ES. DEGREE has in charge to define requirements for future ES portals on Grid.
Report on the experience (or the proposed activity). It would be very important to mention key services which are essential for the success of your activity on the EGEE infrastructure.
From a very large number of existing ES portals, a survey was done to focus on, analyze and document those of particular interest and relevance. The focus is on ES portals which are employing, to a greater or lesser extent, some combination of the following relevant technologies and methodologies, Grid, e-collaboration, Service oriented architecture, semantic web and Ontology.
This survey provides a clear picture of wide range of emerging technologies in ES portals. The high-level of web-based portal services, provided to end-users, permit to define requirements to implement them on gLite and develop new ones.
Describe the added value of the Grid for the scientific/technical activity you (plan to) do on the Grid. This should include the scale of the activity and of the potential user community and the relevance for other scientific or business applications
Large sets of ES data are available and distributed all over the world. The data come from satellite, also from ground-based network and sensors aboard balloon, aircraft, and/or rocket. An urgent need has been the organisation of the data, their access with respect to the data policy, and in some cases tools to define the workflow of the application. Some web-based ES portals have appeared with different tools for discovery, download, and local computation . Grid infrastructure offers the capability to explore those large sets that was not done previously due to the computing power limitation and to deploy complex simulation based on a combination of various large sets of data.
The combination of data web services and Grid via a portal will open new fields and discovery by the full exploration of the data. It is not limited to Earth science
