The electron cloud phenomenon in particle accelerators is related to the secondary electron yield of the surfaces in line of sight of the beam. At present, advanced models to predict electron cloud through simulation codes are available and they rely either on experimental data or on parametrizations of the various quantities and dependencies describing the behaviour of electrons impinging on and emitted from the surface. In the present contribution, we review what is well established about these dependencies and which measurements should still be performed.
