In order to make an accurate interpretation of a storm cell, the radar beam should be pointed at the wet
part of the weather cell to record the proper rainfall intensity (color level). The ideal aiming point is just
below the freezing level of the storm. The best way to find this point is to use the Vertical Scan feature. The
antenna tilt angle can be centered on the strongest return area in the vertical scan to get a more accurate
view of the coverage and intensity of the target in the horizontal scan.
