METEOR-3 TOMS OBSERVATIONS OF RABAUL ERUPTION PLUME

Meteor-3 TOMS overflew the eruption plume from Rabaul, New Britain
at 5:38am GMT on September 19, 1994. Preliminary results show SO2 column
amounts no higher than background and a slight column ozone increase in the
same region as the GMS-observed ash plume. The ozone increase is
most likely due to the presence of SO2, but the actual SO2 mass in the
plume is low and difficult to quantify precisely (<50,000 tonnes).
