34	! Description:
35	! ------------
36	! This is an EXAMPLE routine how to read NetCDF particle data output by PALM.
37	! As an example, the mean heigth and radius of all particles are calculated
38	! and output for each output time available on the file
39	!
40	!
41	! Any additonal analyzation requested has to be added by the user by following
42	! the steps given in this example!
43	!
44	!
45	!
