 Maasvlakte is a location close to Rotterdam, The Netherlands, very close to the sea (near-shore).
 
 To determine the wind speed $v_\mathrm{w}$ at the height of the kite and at

+the height of each tether segment, the power law **Stull (2000)** and the log

 square power law, are used. Input parameters are the ground wind speed
 $v_\mathrm{w,ref}$ and the current height $z$ of the kite or tether segment. The
 ground wind speed used in this paper was measured at $z_\mathrm{ref} = 6.0~m$.
