This sample Intensity Facsimile display was generated by PCSodar between the hours of 3 am and 7 am. The time of day (in hours) is plotted on the horizontal scale and height is plotted on the vertical scale. Red areas represent high intensity; black areas represent low intensity. The Intensity Facsimile data are stored by PCSodar as bit-mapped images (.bmp files) which can be viewed and edited with most graphics software. The example shown here is a typical nighttime shear-echo situation that is indicative of stable atmospheric conditions. After sunrise at about 7 am, the intensity pattern begins to change to a thermal echo with relatively high intensities throughout the altitude range interspersed with periods of rapidly decreasing amplitude, which is characteristic of convective mixing conditions. |
