...I think it's reasonable: I don't have very clear [i]how[/i] to estimate the seasonality of volatility and at the same time been consistent with market cumulative vols.

In the past I've been dealing with price processes which incorporate seasonality (power models like Lucia Scwhartz) but I don't have many clues on how to do it on volatility.

If there's any reference/paper would be very welcome!

thks all

Calibration will not be easy!

Take a look at this paper,

but you can also look into GARCH type models for estimating the seasonality of volatility.
