The relationship of atmospheric data gathered from three-axis bistatic sounders operating at 1, 2, and 4 kHz, and a 2-kHz three-axis monostatic sounder is presented. Wind profiles are computed using the complex covariance function of the returned signal to estimate the power spectrum mean frequency. The backscatter data are presented as high quality grey scale and pseudocolor temperature structure. The data were gathered over varied terrain from Texas to Alaska and represent a sample of common and unique planetary boundary layer events including: ground radiation inversions; elevated subsidence inversions showing shear and convection stresses; gravity wave trains; and convection cells correlated with vertical winds. Several unique events are presented including an isolated large amplitude gravity wave (>600 m) associated with a frontal passage and a radiation inversion with an associated low level jet producing extreme low level shear (≈12 m s-1/150 m). The computational techniques and the associated geometry and frequency are compared to a previously published overview [E. H. Brown and F. H. Hall, Jr., Rev. Geophys. Space Phys. 16, (1) 47–110].
