Scaling transition for long-range dependent Gaussian random fields

In Puplinskaitė and Surgailis (2014) we introduced the notion of scaling transition for stationary random fields X on Z2 in terms of partial sums limits, or scaling limits, of X over rectangles whose sides grow at possibly different rate. The present paper establishes the existence of scaling transition for a natural class of stationary Gaussian random fields on Z2 with long-range dependence. The scaling limits of such random fields are identified and characterized by dependence properties of rectangular increments.
