  I think this is the very same project shown in this month's Scientific
American.  I don't still have it, but take a look.  There was (is) a
project, with parts sources, for people to figure out how much UV is
measureable, so presumably you can get some data to predict the end of the
ozone layer and the end of life on the planet.  It mentioned the use of some
filters, too, and sources for them.
