Abstract

The Experimental Measurement Campaign (XMC) for Planetary Boundary Layer (PBL) Instrument Assessment (XPIA) is a DOE funded study to develop and validate methods of making three dimensional measurements of wind fields. These techniques are of interest to study wind farm inflows and wake flows using remote sensing instrumentation. The portion of the experiment described in this presentation utilizes observations from multiple Doppler wind lidars, soundings, and an instrumented 300m tower, the Boulder Atmospheric Observatory (BAO) in Erie, Colorado.

Highlights

Knowledge of the time evolving, three dimensional wind field is essential in developing and evaluating large eddy simulation (LES) models, the study of turbine wake effects, and optimization of turbine layout for wind farms.A network of scanning, pulsed, Doppler wind lidars can be used to measure the wind speed over a common volume or along a common vertical line (virtual towers (Calhoun, 2006))
