                         RESUME / ABSTRACT

The Experimental Studies section of the Air Quality Research Division (ARQX)
is where Environment Canada studies the ozone layer and the UV Index.  We'll
discuss three different ways that the ozone layer is measured: 
  - the Brewer Ozone Spectrophotometer and its predecessors; 
  - Ozonesonde balloons;
  - Satellites.

After the measurements are taken, we'll show how they are quality-controlled
and merged in the archive of the World Ozone and Ultraviolet Radiation Data
Centre (WOUDC), which is an official archive of the World Meteorological
Organization and is administered by ARQX.

The physics and mathematics will be very general.
