42! Description:
43! ------------
44! This is an EXAMPLE routine how to read NetCDF particle data output by PALM.
45! As an example, the mean heigth and radius of all particles are calculated
46! and output for each output time available on the file
47!
48!
49! Any additonal analyzation requested has to be added by the user by following
50! the steps given in this example!
51!
52!
