3 plots are included here:

1) avg_size_o3hole79-95.ps

This is a plot of the average ozone hole size for years since 1979.
The size is based on the area contained by the 220 DU contour.  The 220
DU contour is used since it is in the sharp gradient region of the hole
(i.e., values are falling off steeply towards the south pole), and
there are no historical measurements below 220 DU prior to 1979.  I
average these daily size estimates between the dates of 2 and 18
October for each year.  The `error bars' are actually the range of
values for the data between 2 and 18 October, and the yellow dots are
the average values.  I have also superimposed the area of the North
American and Antarctic continents on the graph to give some size
perspective.  The data are from the Nimbus-7  TOMS (79-92), Meteor-3
TOMS (93-94), and NOAA SBUV (1995).

2) hbtomsv6_color.ps

This plot shows the minumum value of the October averages for the
satellite data from 1979 to the present, superimposed on the British
Antarctic Survey (BAS) Halley Bay monthly mean Dobson spectrophotometer
measurements (courtesy of Jonathan Shanklin).  The 70-72 data are from
the BUV instrument, the 79-92 data are from the Nimbus-7 TOMS, and the
93-94 data are Meteor-3 observations.

3) o3Oct_70717279_92939495sp_nasa.ps

This plot shows a series of false color images of total ozone over
Antarctica for the years 1970-1971 (BUV), 1979 and 1992 (Nimbus-7),
1993 and 1994 (Meteor-3), and 1995 (NOAA SBUV).
