Check out this link to our South Pole camera!  It shows a picture of the Amundsen-Scott South Pole Station taken every 15 minutes (if a relay satellite is available for transmission).  The camera is attached to the roof of the National Science Foundation’s Atmospheric Research Observatory (ARO), which houses NOAA/ESRL’s Clean Air Facility where measurement… Read More


Measuring Ozone in the Atmosphere The majority of ozone in the atmosphere is found high above the surface in the “Ozone Layer.”  Stratospheric ozone is typically measured as Total Column Ozone, a number representing all the ozone molecules located in a column of air extending from the surface all the way to the edge of… Read More


The Ozone Layer is the name given to naturally occurring high concentrations of ozone located high up in the stratosphere between 35,000 – 160,000 feet.  The ozone layer is important to life on Earth because of its ability to filter out harmful doses of ultraviolet light from the Sun that has the ability to damage… Read More

By Irina Petropavlovskikh, Secretary of the International Ozone Commission and a CIRES and NOAA scientist September 16th is International Day for the Preservation of the Ozone Layer, commemorating the 1987 anniversary of the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer. Hailed as an example of exceptional international cooperation for the… Read More


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


By Refael Klein, NOAA Corps officer, from South Pole, October 3 The sun sits two fingers above the horizon.  It is obscured by fine, white, icy clouds, but nonetheless you can make out its circular shape—dimming and brightening with each gust wind and slight fluctuation in temperature.  Pulsing, blinking, fluttering, stuttering, in a dead language,… 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


  By Irina Petropavovskikh, CIRES and NOAA scientist, from Boulder, September 23 This morning’s e-mail arrived with the first of the World Meteorological Organization’s (WMO) 2016 Antarctic Ozone Bulletins. These bulletins discuss the processes that affect formation of the ozone hole and the status of the ozone layer over the entire Antarctic continent Here’s a short excerpt from the  Antarctic Ozone Bulletin no. 1,… 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
