<abstract>
<p>Monoterpenes are an important class of biogenic hydrocarbons that influence
ambient air quality and are a principle source of secondary organic aerosol
(SOA). Emitted from vegetation, monoterpenes are a product of photosynthesis
and act as a response to a variety of environmental factors. Most
parameterizations of monoterpene emissions are based on clear weather models
that do not take into account episodic conditions that can drastically
change production and release rates into the atmosphere. Here, the
monoterpene dataset from the rural Thompson Farm measurement site in Durham,
New Hampshire is examined in the context of a set of known severe storm
events. While some storm systems had a negligible influence on ambient
monoterpene mixing ratios, the average storm event increased mixing ratios
by 0.59 ± 0.21 ppbv, a factor of 93% above pre-storm levels. In some
events, mixing ratios reached the 10&apos;s of ppbv range and persisted
overnight. These mixing ratios correspond to increases in the monoterpene
emission rate, ranging from 120 to 1240 g km&lt;sup&gt;−2&lt;/sup&gt; h&lt;sup&gt;−1&lt;/sup&gt; compared to an
estimated clear weather rate of 116 to 193 g km&lt;sup&gt;&amp;minus;2&lt;/sup&gt; h&lt;sup&gt;−1&lt;/sup&gt;.
Considering the regularity of storm events over most forested areas, this
could be an important factor to consider when modeling global monoterpene
emissions and their resulting influence on the formation of organic
aerosols.</p>
