Correlation of in-flight displacement damage on the OSL sensor with space environment on-board Jason-2 spacecraft

Displacement damage doses measured by the ICARE-NG/OSL sensor on board the French JASON2 spacecraft from CNES, the French space agency, are compared to predictions performed with (1) proton measurements performed with the spectrometers on board the same spacecraft/instrument and (2) protons spectrum predicted by the legacy AP8min model and the future AP9 perturbed model.
