The SEPServer project will address the topic SPA.2010.2.1-03, Exploitation of space science and exploration data, of the call FP7-SPACE-2010-1. Through its impact, the project may also support other projects funded through the topic SPA.2010.2.3-01, Security of space assets from space weather events.The main objective of the SEPServer project is to produce a new tool, which greatly facilitates the investigation of solar energetic particles (SEPs) and their origin: a server providing SEP data, related electromagnetic (EM) observations and analysis methods, a comprehensive catalogue of the observed SEP events, and educational/outreach material on solar eruptions.The SEPServer project is coordinated by Dr. Rami Vainio, University of Helsinki. The project will combine data and knowledge from 11 European partners and several collaborating parties from Europe and US. The work is organised in 7 work packages (WPs): 1 Management; 2 SEP observations; 3 EM observations; 4 Simulations and inversion tools; 5 Scientific data analysis; 6 Server development; and 7 Dissemination and external coordination. WPs 2-5 provide data and analysis tools to the server development (WP6); the scientific data analysis (WP5) then makes use of these data and tools making sure that they meet the needs of the lead users.SEPServer will add value to several space missions and earth-based observations by facilitating the coordinated exploitation of and open access to SEP data and related EM observations, and promoting correct use of these data for the entire space research community. This will lead to new knowledge on the production and transport of SEPs during solar eruptions and facilitate the development of models for predicting solar radiation storms and calculation of expected fluxes/fluences of SEPs encountered by spacecraft in the interplanetary medium. SEPServer will, thus, add value to the national and European activities by combining them to a comprehensive space storm analysis service.
