<strong>wradlib</strong>.clutter.histo_cut(prec_accum)<br />
Histogram based clutter identification.<br />
This identification algorithm uses the histogram of temporal accumulated rainfall. It iteratively detects classes<br />
whose frequency falls below a specified percentage (1% by default) of the frequency of the class with the<br />
biggest frequency and remove the values from the dataset until the changes from iteration to iteration falls<br />
below a threshold. This algorithm is able to detect static clutter as well as shadings. It is suggested to choose<br />
a representative time periode for the input precipitation accumulation. The recommended time period should<br />
cover one year.<br />
Parameters prec_accum : array_like<br />
spatial array containing rain accumulation<br />
Returns output : array<br />
boolean array with pixels identified as clutter/shadings set to True.<br />

3.11 Vertical Profile of Reflectivity (VPR)<br />
UNDER DEVELOPMENT<br />
Precipitation is 3-dimensional in space. The vertical distribution of precipitation (and thus reflectivity) is typically<br />
non-uniform. As the height of the radar beam increases with the distance from the radar location (beam elevation,<br />
earth curvature), the one sweep samples from different heights. The effects of the non-uniform VPR and the differnt<br />
sampling heights need to be accounted for if we are interested in the precipiation near the ground or in defined heights.<br />
This module is intended to provide a set of tools to account for these effects.<br />
