Description:
Many long-term monitoring sites in Antarctic regions, which deploy ground-based stratospheric remote sensors and fly radiosondes
or ozonesondes on balloons, supported the Airborne Polar Experiment in September and October 1999. Support consisted
of supplying data to the campaign in real time, and in some cases by increasing the frequency of measurements during the campaign.
The results will strengthen scientific conclusions from the airborne measurements. But results from these sites are allowing important
scientific studies of new aspects of the ozone hole in their own right, because like the aircraft and its campaign, many sites traverse
the vortex edge and are close to the largest source of lee waves, or measure infrequently observed trace gases such as HNO3. Examples
of such studies are the behaviour and value of NO2 in midwinter, ozone filamentation with no apparent horizontal advection,
the frequency and amplitude of gravity waves over the Antarctic Peninsula, mixing in the lowest stratosphere in Antarctic spring, the
mechanism and frequency of HNO3 enhancement above the ozone peak in midwinter, and trends in UV dose in southern South
America.
