We present two new challenges related to the stochastic downscaling method SDM that we applied to wind simulation refinement in \cite{BBCDRS08}. After setting the framework, we introduce the boundary forcing issue, and propose a numerical scheme adapted to Particle in Cell methods. Then we turn to the uniform density constraint raised by SDM and propose some new methods that rely on optimization algorithms.
