<abstract>
<p>Sulfur dioxide emissions from Popocatépetl volcano in central Mexico
were measured during the MILAGRO field campaign in March 2006. A stationary
scanning DOAS (Differential Optical Absorption Spectrometer) was used to
monitor the SO&lt;sub&gt;2&lt;/sub&gt; emissions from the volcano and the results were
compared with traverses done with a COSPEC from the ground and a DOAS
instrument on board an ultra-light aircraft. Daytime evolutions as well as
day-to-day variation of the SO&lt;sub&gt;2&lt;/sub&gt; emissions are reported. A value of 2.45&amp;plusmn;1.39 Gg/day of SO&lt;sub&gt;2&lt;/sub&gt;
is reported from all the daily averages
obtained during the month of March 2006, with large variation in maximum and
minimum daily averages of 5.97 and 0.56 Gg/day, respectively. The large
short-term fluctuations in the SO&lt;sub&gt;2&lt;/sub&gt; emissions obtained could be
confirmed through 2-D visualizations of the SO&lt;sub&gt;2&lt;/sub&gt; plume measured with a
scanning imaging infrared spectrometer. This instrument, based on the
passive detection of thermal radiation from the volcanic gas and analysis
with FTIR spectrometry, is used for the first time for plume visualization
of a specific volcanic gas. A 48-h forward trajectory analysis indicates
that the volcanic plume was predominately directed towards the
Puebla/Tlaxcala region (63%), followed by the Mexico City and
Cuernavaca/Cuautla regions with 19 and 18% occurrences, respectively.
25% of the modeled trajectories going towards the Puebla region reached
altitudes lower than 4000 m a.s.l. and all trajectories remained over this
altitude for the other two regions.</p>
