Hi Marco-

>(x,y,z) and the concentrations need to be represented as points (in

If you have a set up points with lat,lon,alt, you should be able to 
display this as point data. You can create a station model which would
have a shape (e.g., sphere) colored by variable and sized by concentration.

At present, the netcdf file would have an index as the unlimited
dimension with the lat,lon,alt,time and variables as part of the
index.

We are working on a new way to import point data and if you have
some specific format that you are currently working on, it would be
a good test for this new access.
