Such changes are a marked departure from past average levels of ozone, which have kept within a narrow window of values since the launch of Nimbus-7 in 1979.
Heath's analysis of data from instruments aboard the Nimbus-4 and Nimbus-7 satellites shows that global ozone levels have been decreasing and, as predicted by ozone models, the depletion rates have been the greatest in the high latitudes and polar regions.
Krueger and his colleagues at NASA Goddard Space Flight Center in Greenbelt, Md., were puzzled by a large blob in the map made from data recorded by the Total Ozone Mapping Spectrometer (TOMS) aboard the Nimbus-7 statellite as it passed over Mexico.
Intrigued by Farman's finding, Stolarski and others rummaged through the reams of data taken by an instrument called the Total Ozone Mapping Spectrometer (TOMS) on the polar-orbiting Nimbus-7 satellite launched by NASA in 1978.
