Dobson on the ozone


  • Anonymous


Editor's Note: It is appropriate for the geophysical community this year to remember the work of G. M. B. Dobson, a pioneer in atmospheric ozone research, on the 100th anniversary of his birth in 1889. A recent resurgence of interest in depletion of stratospheric ozone and the role of chlorofluorocarbons has been sparked by the report of Farman et al. [1985], who found a steady decrease in the October mean total ozone concentrations over Antarctica since the 1970s, from ∼300 to ∼180 Dobson units (1 Dobson unit = 1 matm cm of ozone). A special session A07, entitled “Ozone Depletion in the Polar Stratosphere” will be held at the 1989 Spring AGU meeting in Baltimore, Md. The paragraph below from Dobson [1968] was brought to our attention by M. Nicolet, Brussels, Belgium.
