Bulletin
Antarctic ozone today:
The 2024 ozone hole began to appear in late August and has grown
rapidly. It now covers 4 million square kilometres (msqkm). The
temperature of the ozone layer over Antarctica is near the annual
minimum, with air descending over the south pole. The
temperature of the ozone layer is
warmest over the Southern Ocean and declines towards the equator and
pole. The 2024 polar vortex began to form in late April, a little
earlier than usual. It has grown and currently has an area of around
30 msqkm, close to the usual area. Within the vortex the temperature
is now well below the -78°C
Polar Stratospheric Clouds (PSC) formation threshold. The area with
potential PSCs began to grow from mid May and reached 24 msqkm in
late July. Some warming events then took place around the time when
the area is usually at its peak. It is currently around 22 msqkm,
close to usual for the time of year. Overall the system remains
relatively unstable, with significant wave activity. There are signs
that this year we may have a split ozone hole, such as appeared in
2002. Ozone
values are a little lower over the continent and higher over the
southern ocean. They currently range from a low of around 170 Dobson
Units (DU) to a high of nearly 500 DU.

temperature of the ozone layer is
warmest over the Southern Ocean and declines towards the equator and

earlier than usual. It has grown and currently has an area of around
29 million square kilometres (msqkm), close to the usual area.
Within the vortex the temperature is now well below the -78°C
Polar Stratospheric Clouds (PSC) formation threshold. The area with
potential PSCs began to grow from mid May and reached 24 msqkm in
late July. Some warming events then took place and it is currently
around 23 msqkm, a somewhat smaller than usual for the time of year.
Overall the system remains relatively unstable, with significant
wave activity. Ozone
values are a little lower over the continent and higher over the
southern ocean. They currently range from a low of around 240 Dobson
Units (DU) to a high of around 430 DU.

Antarctic ozone today:
The temperature of the ozone layer over Antarctica is falling
and air is descending over the south pole. The temperature of the
ozone layer is warmest over the Southern Ocean and declines towards

an area of around 22 million square kilometres (msqkm), close to the
usual area. Within the vortex the temperature is now below the -78°C
