Turbulence properties of a cold Mach 0.85 are studied through the use of Particle Image Velocimetry data. The data were acquired through two separate experiments; one with the light sheet orientated in the streamwise direction and one with the light sheet perpendicular to the flow directions. The use of PIV data allowed for the study of two-point spatial correlations that are shown to be relevant to the noise production. Examination of these spatial correlations allow for the evaluation of terms important in the application of Lighthill's analysis, although to fully evaluate this we will need space-time correlations which are not currently available from experiments. The examination of the spatial correlations showed how the turbulent structure of the jet evolves in the streamwise and radial directions throughout the noise producing region. Specifically, this effort concentrates on presenting these spatial correlations.
