Products developed in the frame of the CALIPSO mission are now widely used in the scientific community. They are gaining in quality and in perimeter to better address scientific needs. In this project we aim to describe the follow-up activities related to the development of the operational CALIOP / IIR algorithms, of some science algorithms, the validation and comparison of related products as well as their implications for CGTD ICARE and the objectives of the CALIPSO mission.
