We consider the stochastic heat equation whose solution is observed discretely in space and time. An asymptotic analysis of power variations is presented including the proof of a central limit theorem. It generalizes the theory from Bibinger and Trabs (Volatility estimation for stochstic PDEs using high-frequency observations, 2017) [2] in several directions.
