to the web site of the CRATERRE project .
CRATERRE is a project
funded by CNES, the french space agency. The goal
of the project is to develop new radiation belt models allowing a better description
of the space environment (electron and proton) for mission specifications.
Three axes of research will be conducted all along the study by ONERA-DESP:
Physical modeling (Salammbo)
Specification model (From POLE
On this web site you will find:
Ionising Particle in Space Analysis Tool (IPSAT) is a virtual observatory.
A radiation belt data base has been developped and is being growing. Then a web interface to plot the data in many different ways and to
compare them between different spacecraft on different orbits is provided.
A description of the CNES-ONERA ICARE radiation monitor is provided
A restricted area to the project team.

|The image below provides an overview
of space environment: top panel=solar protons measured by GOES, the second panel from top=Kp magnetic activity
index and next three panels=electrons (differential omnidirectional 1.6 MeV) and protons (
integral omnidirectional > 97 MeV and differential omnidirectional 27 MeV) in a L versus time plot along JASON3 orbit.
||The image below provides alarms of space environment: top panel=Solar Proton Event alarm, the middle panel=radiation belt
index for medium energy electron in the outer belt and bottom panel=radiation belt
index for high energy electron in the outer belt
