The OLCI instrument principle is very similar to that of MERIS, with numerous improvements. Most of the methods derived for MERIS calibration are directly applicable to OLCI and will be briefly listed. The status of on-ground characterization and calibration will be summarized and discussed. Performances will be presented. The strategy regarding instrument calibration from in-flight measurements will be presented. Methodologies dedicated to radiometric and spectral in-flight calibration will be described and expected performances discussed.
