Poster Presentation
With the drive to reduce wind farm development costs, the use of remote sensing instrumentation to provide short term measurement deployments (<1 year) to supplement a meteorological mast campaign, have proved popular in the industry. The wind speed variation between measurement points can then be used to better understand wind conditions across the wind farm and validate the horizontal extrapolation of wind flow modelling simulations. This study aims to review the potential bias and elevated uncertainty levels that may be introduced when assuming that concurrent wind data measurement periods of less than a year are sufficient to represent the annualized horizontal variation between measurement points. The study will present the bias and uncertainty of the data period duration and time of year and consider the dependence of these statistics relative to site geographic and roughness characteristics, as well as the distance and elevation difference between measurement locations.
