	<abstract content_type="html">A numerical evaluation of global oceanic emissions of α-pinene
and isoprene based on both &quot;bottom-up&quot; and &quot;top-down&quot;
methods is presented. As far as we know, this is the first
quantification of global oceanic emission of α-pinene. We infer
that the global &quot;bottom-up&quot; oceanic emissions of α-pinene
and isoprene are 0.013 Tg C yr&lt;sup&gt;&amp;minus;1&lt;/sup&gt; and
0.32 Tg C yr&lt;sup&gt;&amp;minus;1&lt;/sup&gt;, respectively. By constraining global
chemistry model simulations with the shipboard measurement of Organics
over the Ocean Modifying Particles in both Hemispheres summer cruise,
we derived the global &quot;top-down&quot; oceanic α-pinene source
of 35.1 Tg C yr&lt;sup&gt;&amp;minus;1&lt;/sup&gt; and isoprene source of
2.5 Tg C yr&lt;sup&gt;&amp;minus;1&lt;/sup&gt;. The global oceanic α-pinene source
and its impact on organic aerosol formation is significant based on
&quot;top-down&quot; method, but is negligible based on &quot;bottom-up&quot;
approach. Our research highlights the importance to carry out further
research (especially measurements) to resolve the large offset in the
derived oceanic organic emission based on two different approaches.</abstract>
