Welcome 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:

In-situ measurements
Physical modeling (Salammbo)
Specification model (From POLE to global)

Last month space environment

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
