Often we encounter a misunderstanding based on the assertion that the
criterion of air quality is excluded from studies into meteorology and
climatology. In contrast to this, it must be stressed that the admixt
ures and pollutants pertaining to air quality criteria belong to the a
tmosphere and therefore, of course, to the field of meteorology, and d
ue to their possible effects also to human biometeorology. A normal we
ather forecast should include data concerning the concentrations of oz
one, nitrogen dioxide, and other substances. Biometeorological weather
classifications should also include mention of air quality rather mor
e than previously. For instance, the classification after Bucher used
in Germany is referred to and supplemented with respect to air quality
. Analogous relationships hold true for the global classification of c
limates. As an example, the well-known classification after Koeppen is
supplemented according to air quality.
