| Zusammenfassung |
| While the field of atmospheric organic aerosol scientific research has
experienced thorough and insightful progress over the last half century,
this progress has been accompanied by the evolution of a communicative and
detailed yet, at times, complex and inconsistent language. The menagerie of
detailed classification that now exists to describe organic compounds in our
atmosphere reflects the wealth of observational techniques now at our
disposal as well as the rich information provided by state-of-the-science
instrumentation. However, the nomenclature in place to communicate these
scientific gains is growing disjointed to the point that effective
communication within the scientific community and to the public may be
sacrificed. We propose standardizing a naming convention for organic aerosol
classification that is relevant to laboratory studies, ambient observations,
atmospheric models, and various stakeholders for air-quality problems.
Because a critical aspect of this effort is to directly translate the essence
of complex physico-chemical phenomena to a much broader, policy-oriented
audience, we recommend a framework that maximizes comprehension among
scientists and non-scientists alike. For example, to classify volatility, it
relies on straightforward alphabetic terms (e.g., semivolatile, SV;
intermediate volatility, IV; etc.) rather than possibly ambiguous numeric
indices. This framework classifies organic material as primary or secondary
pollutants and distinguishes among fundamental features important for
science and policy questions including emission source, chemical phase, and
volatility. Also useful is the addition of an alphabetic suffix identifying
the volatility of the organic material or its precursor for when emission
occurred. With this framework, we hope to introduce into the community a
consistent connection between common notation for the general public and
detailed nomenclature for highly specialized discussion. In so doing, we try
to maintain consistency with historical, familiar naming schemes, unify much
of the scattered nomenclature presented in recent literature, reduce the
barrier of comprehension to outside audiences, and construct a scaffold into
which insights from future scientific discoveries can be incorporated. |
