Welcome to ESA's Solar Energetic Particle Environment Modelling (SEPEM) application server, a WWW interface to solar energetic particle data and a range of modelling tools and functionalities intended to support space mission design.
The system provides an implementation of several well known modelling
methodologies, built on cleaned datasets. A large number of datasets
have been combined into an SQL database for easy access. SEPEM also
gives the user increased flexibility in his/her analysis and allows
generation of mission integrated fluence statistics, peak flux
statistics and other functionalities. It also integrates effects tools
that calculate single event upset rates and radiation doses for a
variety of scenarios; the statistical methods can further be applied to
these effects parameters.
Furthermore, SEPEM makes use of a newly developed physics-based
shock-and-particle model to simulate particle flux profiles of gradual
SEP events from Mercury to Mars orbits [SOLPENCO2, SOL2UP].
A contiguous reference proton data set was constructed using data ranging from 1973 to
2015, by means of data cleaning and processing tools available on the server.
Using this dataset, a reference event list was constructed and also made
available on the server.
An extensive set of help pages is available, including background
material, information on the datasets and processing, and context
sensitive help for each application page. Please consult the help pages
before using the system!
Use of SEPEM is free of charge, but registration is required and can be
done from the homepage using the link at the bottom of the left-hand
menu. For further information please contact
N. Crosby. Please consult the
server usage help page before registering for an account: registration implies acceptance of the terms and conditions outlined there.
