The magnetopause is the outer border of the magnetosphere. It is responsible for mass and energy transfer of the shocked solar wind into the magnetosphere. The transfer rates can be increased by, e.g., diffusion due to the resonant wave-particle interaction. With the help of the four CLUSTER spacecraft we investigate the properties of wave turbulence and estimate the possible diffusion rates for magnetopause sheets with different thicknesses.
