Surface wind observations from insitu and remote instruments (buoys and scatterometers) are characterized by different scales and measurement errors, which can be estimated with the triple collocation method (Stoffelen, 1998). In a previous study we assessed the errors of the different wind products using collocations of buoys, scatterometer and ECMWF model output (Cossu et al., 2021). In this study, we extend the triple collocation analysis to tropospheric winds (4D winds) using collocations of aircraft observations (Mode-S), vertical wind profiles from the Aeolus satellite mission (Fig. 1) and ECMWF model output

This work was done in the framework of the EUMETSAT fellowship “On the 4-D Consistency of Satellite Wind Products for Regional NWP Data Assimilation (WIND-4D)”
