Dear Heinke,

     if constituent='ozone' is in the data, then how do you deal with a
file that has several constituents in it? This is the norm rather than
the exception in chemistry modelling. If you suggest
     constitutent = '[ozone, NO2, CO, ...]'; (or something like this
in correct syntax)
then I believe it will be impractical to construct this constituent
vector. If at all, then I think the constituent name must come along
with the variable attributes.


Best regards,

Martin
