BASE threshold value

The configurable threshold value defines the minimum reflectivity that must present to be displayed in the image.

The first of the following images shows BASE with a -20 dBZ threshold defined. In this image, the lower, less dense cloud is shown in the displayed image.

In the second image, with a 40 dBZ threshold, the lower cloud is not shown in the displayed image because its reflectivity value is lower than the defined threshold.
