  • Estimates of lateral dispersion parameters in low wind speed conditions

    Wind speed time series recorded during stable low wind speed conditions are typically non–stationary, with large horizontal oscillations, commonly known as meandering. In this paper, two wavelet–based methods are proposed to obtain lateral dispersion coefficients from such time series. These methods, associated with a specific wind model, have been tested by using wind velocities recorded, with ...

  • Introducing The RNRG Goalpost Boom

    We are happy to introduce a new goalpost mounting solution for installing redundant class 1 anemometers. This new boom, designed specifically for use with our 80m XHD TallTower, positions anemometer cups at exactly 80 m above ground level—2.5 m away from each other—and 1.99 m ...

  • Effects of spatial filtering, prefiltering, and aliasing in measurements from applied technologies` Sonic K-Probe

    The Applied Technologies' Inc. (ATI) K-probe measures wind components along three mutually orthogonal axes separated spatially from each other to minimize flow distortion errors. The sonic anemometer samples the wind at a 100-Hz rate but constructs 0.1-s (10-point) non-overlapping block averages to provide. a 10-Hz data train for internal processing. This digital prefiltering is designed to ...

  • Momentum Flux: Gross, Scalar, Alongwind, or Net?

    Modern micrometeorology is an amalgam of two traditions: one arises from field measurements in the open atmosphere and another from wind tunnel experiments. Early micrometeorological field work, and even relatively recent studies (viz. the von Karman constant experiments by Frenzen and Vogel, 1995), were done with precision cup anemometers, which can only provide a scalar speed measurement. Most ...

  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • How RNRG`s Hybrid XT Solutions Can Keep Your Turbine Output from Freezing Over This Winter

    At RNRG’s headquarters in Hinesburg, Vermont, the hillsides are painted with the vibrant hues of autumn. While breathtakingly beautiful, nature’s colorful display is also a reminder that winter is right around the corner. As the first frost looms, now is the perfect time to consider Hybrid XT Turbine Control ...
