[3434]	116	! Description:
	117	! ------------
[4400]	118	!> The module acts as an interface between 'real-world' observations and
[3471]	119	!> model simulations. Virtual measurements will be taken in the model at the
[4400]	120	!> coordinates representative for the 'real-world' observation coordinates.
[3471]	121	!> More precisely, coordinates and measured quanties will be read from a
[4400]	122	!> NetCDF file which contains all required information. In the model,
[3471]	123	!> the same quantities (as long as all the required components are switched-on)
	124	!> will be sampled at the respective positions and output into an extra file,
[4400]	125	!> which allows for straight-forward comparison of model results with
	126	!> observations.
