In general, for the purposes of C.R. 107.4h, which defines S, the additional mana produced with Glittering Frost is "mana ... produced by a snow source", even if the enchanted land isn't a snow land, since Glittering Frost has the snow supertype (C.R. 205.4f; compare Glittering Frost with Winter's Night, which isn't a snow source). (In fact, there is no such thing as "snow mana"; "[s]now is neither a color nor a type of mana" [C.R. 107.4h].) See also this thread.
