  <dc:description>&lt;p&gt;&lt;span&gt;We present an airborne method that eliminates or minimizes several disadvantages of the customary plume cross-section sampling method for determining volcanic CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&lt;span class="Apple-converted-space"&gt;&amp;nbsp;&lt;/span&gt;emission rates. A LI-COR CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;analyzer system (LICOR), a Fourier transform infrared spectrometer system (FTIR), and a correlation spectrometer (COSPEC) were used to constrain the plume CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;/SO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&lt;span class="Apple-converted-space"&gt;&amp;nbsp;&lt;/span&gt;and the SO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&lt;span class="Apple-converted-space"&gt;&amp;nbsp;&lt;/span&gt;emission rate. The method yielded a CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&lt;span class="Apple-converted-space"&gt;&amp;nbsp;&lt;/span&gt;emission rate of 300 td&lt;/span&gt;&lt;sup&gt;&amp;minus;1&lt;/sup&gt;&lt;span&gt;&lt;span class="Apple-converted-space"&gt;&amp;nbsp;&lt;/span&gt;(metric tons per day) for Pu&amp;prime;u &amp;prime;O&amp;prime;o cone, Kilauea volcano, on 19 September 1995. The CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;/SO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&lt;span class="Apple-converted-space"&gt;&amp;nbsp;&lt;/span&gt;of 0.20 determined from airborne LICOR and FTIR plume measurements agreed with the CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;/SO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&lt;span class="Apple-converted-space"&gt;&amp;nbsp;&lt;/span&gt;of 204 ground-based samples collected from vents over a 14-year period since the Pu&amp;prime;u &amp;prime;O&amp;prime;o eruption began in January 1983.&lt;/span&gt;&lt;/p&gt;</dc:description>
