During the fall and winter of 1976-77 a project was undertaken to establish the feasibility of using a bivane anemometer to calculate dispersion coefficients from wind fluctuation statistics. The measurements procedure and the experimental results are described in this report. It was determined that the time allowed for the project was insufficient to collect samples of the weather conditions required. The lack of agreement between the concurrent bivane measurements and the vertical dispersion of the plume indicates that care must be taken in applying the bivane results to determine the dispersion of the GCOS plume.
