Satellite image of atmospheric sulphur dioxide (SO2) after the eruption of El Chichon,Yucatan,Mexico. El Chichon erupted on 28 March 1982 & again on the 3rd & 4th of April. This image,the 2nd in a series of 4,relates to data obtained on April 5th by the Total Ozone Mapping Spectrometer (TOMS) on the Nimbus-7 satellite,an instrument normally dedicated to measuring atmospheric ozone. The colour scale at right shows concentration of SO2,with black representing the highest levels. This image shows the SO2 plume's increasing east- west spread; successive images show its enlargement & ultimate dispersal | |
