This article is from the Ozone Depletion: The Antarctic Ozone Hole FAQ, by Robert Parson firstname.lastname@example.org with numerous contributions by others.
A remark on references: they are neither representative nor
comprehensive. There are _hundreds_ of people working on these
problems. For the most part I have limited myself to papers that
are (1) widely available (if possible, _Science_ or _Nature_ rather
than archival sources such as _J. Geophys. Res._) and (2) directly
related to the "frequently asked questions". This gives very short
shrift to much important work; for example, I say very little about
stratospheric NOx, even though a detailed accounting of chemistry
and transport of the nitrogen oxides is one of the major goals
of current research. Readers who want to see "who did what" should
consult the review articles listed below, or, if they can get them,
the extensively documented WMO reports.
