<P>In collaboration with scientists from the University of Cambridge and from Scripps Institution of Oceanography, we tested our mini-DOAS in the field to measure SO<SUB>2</SUB> flux in the plume of Masaya volcano.  This was a relatively new instrumental method at the time.</P>

<P>In addition, we were able to use three mini-DOAS instruments in conjunction to measure the plume speed of Masaya, information that is critical to an accurate flux measurement, but in the past had been difficult to obtain.</P>
