This paper describes the damage occurring in CCDs exposed to solar radiation and explains its implications for the Gaia measurements by focusing on the astrometric instrument. It introduces the strategy that will be used in the Gaia data processing to mitigate the radiation induced effects, and presents CEMGA (CTI effects Models for Gaia) a multi-purpose platform which hosts different models that simulate radiation effects on CCDs.
