“…Its estimated or "measured" parameters describe the air movement from the information of the wind's direction, orientation, and intensity, as well as the statistics produced based on the sampling techniques of each sensor. Obtaining these parameters basically depends on the physics of the propagation of electromagnetic and acoustic waves [2,3,[6][7][8][9][10][11][12][13].…”

This article seeks to compare the performance of a LIDAR Windcube V2, manufactured by Leosphere, with that of a SODAR MFAS, manufactured by Scintec, in evaluating wind speed at different altitudes. The data from these two sensors were collected at three locations on the Brazilian equatorial margin in the state of Maranhão. The comparison of these sensors aims at their simultaneous use at different points. The horizontal velocity components, by altitude, showed Pearson correlation values above 0.9 and values for the vertical velocity component between 0.7 and 0.85. As for the sampling efficiency, the LIDAR had a performance slightly higher than that of SODAR, especially at the point closest to the coast. In general, both sensors showed similar values, despite the differences in sampling methods. The results showed that the joint performance of these sensors had good correlation, being reliable for application in estimating wind potential for power generation in coastal areas of the equatorial region.

“…Additionally, some relevant research devoted to sonic anemometers has been carried out at IDR/UPM [35][36][37][38][39]. Although other wind speed sensors such as the aforementioned sonic anemometer, LIDAR, SODAR, and nacelle anemometers, have been thoroughly developed and studied in order to substitute the cup anemometer along the past decades [40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59], this old fashioned but robust and reliable instrument (see Figure 1) developed by T.R. Robinson in the 19th century [60][61][62][63], remains the most demanded and used wind sensor for meteorologists and within the wind energy sector.…”

Abstract:In the present work, the research derived from a wide experience on cup anemometer calibration works at IDR/UPM Institute (Instituto Universitario de Microgravedad "Ignacio Da Riva") is summarized. This research started in 2008, analyzing large series of calibrations, and is focused on two main aspects: (1) developing a procedure to predict the degradation level of these wind sensors when working on the field and (2) modeling cup anemometer performances. The wear and tear level of this sensor is evaluated studying the output signal and its main frequencies through Fourier analysis. The modeling of the cup anemometer performances is carried out analyzing first the cup aerodynamics. As a result of this process, carried out through several testing and analytical studies since 2010, a new analytical method has been developed. This methodology might represent an alternative to the classic approach used in the present standards of practice such as IEC 64000-12.
