Short summary
The paper presents estimates of aircraft-derived wind observations obtained using Mode-S EHS method by applying the triple-collocation technique. Triple-collocated data sets were constructed using sodar (at Schiphol airport) and Doppler radar wind observation (from two radars in the Netherlands) in combination with numerical weather model data. It was found that the wind error near the surface is around 1.4 m s−1, while at 500 hPa the error is estimated to be around 1.1 m s−1.
