About the Cover:

Total ozone distribution over the southern hemisphere is illustrated on the cover for October 3, 1979, at the onset of the "ozone hole" phenomenon and on the same date four years later, in 1983; this phenomenon is discussed in the article by Elliot and Rowland which begins on page 387. The images are from the Total Ozone Mapping Spectrometer (TOMS) instrument on board the Nimbus 7 satellite. Color coding spans the range 150-600 Dobsons, or, 0.150-0.600 atm-cm. The Dobson can be converted to more accessible measures of integrated column density, such as molecules/cm2 through the ideal gas law.
