These instruments can be moved from turbine to turbine to perform cost-effective power curve measurements, performance monitoring and the adjustment of turbine static parameters.

Thus, physical modelling of atmospheric boundary layer (ABL) flow over hills is useful in many research areas, such as wind energy assessment. But, and it is a big but, the proper quality of physical experiments is the prerequisite.
