[3434]	122	! Description:
	123	! ------------
[4498]	124	!> The module acts as an interface between 'real-world' observations and model simulations.
	125	!> Virtual measurements will be taken in the model at the coordinates representative for the
	126	!> 'real-world' observation coordinates. More precisely, coordinates and measured quanties will be
	127	!> read from a NetCDF file which contains all required information. In the model, the same
	128	!> quantities (as long as all the required components are switched-on) will be sampled at the
	129	!> respective positions and output into an extra file, which allows for straight-forward comparison
	130	!> of model results with observations.
