The 2016 formation of the Antarctic Ozone Hole turned out to be fairly “average.”  After 2015, where an incredibly stable polar vortex held the depletion region together well in to December, NOAA scientist were curious how 2016 would progress.  Although the vortex remained fairly stable and circular, the depletion region never quite reached the size seen last… Read More

  With sunrise finally arriving and the South Pole beginning six straight months of daytime, destruction of protective ozone continues high above in the stratosphere.  As can be seen in the plot above, 2016 continues marching toward a minimum measurement of total column ozone during the  annual formation of the Antarctic Ozone Hole.  Scientists at Boulder’s… Read More

With sunrise now only a few days away, NOAA scientists at the South Pole continue to launch balloons high in to the stratosphere to measure the quickly depleting ozone layer overhead.  Free chlorine activated by the long-absent sunlight high in the stratosphere is currently destroying large swaths of protective ozone.   The instrument on this balloon… Read More
