Measurements of wind direction and velocity at and near the Cabauw meteorological tower are disturbed by the tower, a measuring building and various supporting constructions. Potential flow theory has been used to describe the flow around these obstacles and along their downwind wakes. The presence of a wake contributes significantly to the size of the measuring errors. Correction formulae are presented for the Cabauw data set of the years 1973-1984. These results have been validated by comparing simultaneous measurements at different Instrument positions.
