I saw the code, which generates the intensity image, set all values larger than 255 to 255. Does that mean the range of intensity and reflectivity is from 0 to 255? But the intensity image seems to saturate a lot. And the value of reflectivity and intensity seems equal.

Web1. feb 2006 · The comparisons spanned radar reflectivity values from −15 to +20 dB Z, ice water contents (IWCs) from 0.01 to 0.4 g m −3, and median volumetric diameters between 0.2 and 3 mm. In mixed-phase conditions the agreement is much poorer because of the higher-density ice particles present. WebIf you use a Reflectivity mask in the Alpha Channel of the Normal Map (See section 6.5 below), slider values of 0.0 correspond to no reflections and 1.0 corresponds to whatever the grayscale value of the Reflectivity mask is. Slider values above 1.0 will multiply the Reflectivity mask value by 1x to x2 (the result is capped at 2.0).
