THICK threshold value

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

The first of the following images shows THICK with a -20 dBZ threshold defined. In this image, more data is displayed in the image, including the lower, less dense cloud content.

In the second image, with a 40 dBZ threshold, a much smaller set of data comprising only cloud cover with a reflectivity of 40 dBZ or higher, is displayed.
