Measuring atmospheric turbulent structure constants is important for the quantification of sound propagation within the atmosphere. During the summer of 2016, the authors utilized in situ and remote sensing techniques to quantify the structure constants CT**2 AND CV**2 as part of a project to evaluate the impact of sound bursts on a microphone array within a convective boundary layer.  The instruments used were sonic anemometers, one high frequency sodar and one low frequency sodar. In addition, rawinsonde data were used to provide the local mixing height during the experimental period.  This paper presents the analysis of these measurements and some implications for ground level sound intensities from elevated sound sources.
