In this case, only the anemometric data from the windward anemometers is used for the calculations, so half as much valid data as in the former case will be collected per unit of time.
As will be seen in the following two sections, the proposed configuration, combining vehicle-based and track-side anemometric measurements made at a common reference height, is conducive to the application of a novel technique for predicting the free-stream velocity used to 'calibrate' the vehicle-based velocity measurement to free-stream conditions.
Considering the repercussions of an improper account of wind conditions on the assessment of vehicle aerodynamic performance, the calibration of the biased wind velocity readings sensed by a vehicle-mounted anemometer using track-side anemometric measurements is a pivotal step.
T are the "propagators" of the anemometric information.
Figure 13a shows an example of a spectrum computed from the anemometric data acquired during the aerodynamic experiments.
To illustrate the relevance of the proposed method, let us consider a specific example of anemometric data acquired during the present project.
