The Ozone Hole 2025
Antarctic Situation at 2025 July 7 Antarctic
ozone today:
The 2025 polar vortex is
growing and now covers 23 million square kilometres (msqkm).
The area with potential PSCs
began to grow from early May and covers some 22 msqkm, close to the
long term average. The bulk of the ozone layer is now below the
-78°C Polar Stratospheric Clouds (PSC) formation threshold. The
temperature of the ozone layer is warmest around Antarctica and
declines towards the equator and the pole. Ozone values are now
building around the continent and lower over it. They currently
range from a low of around 240 Dobson Units (DU) to a high of around
430 DU.
Antarctic Situation at
2025 June 23
Antarctic ozone today:
The 2025 polar vortex is beginning to form and has grown to
20 million square kilometres (msqkm). The area with potential PSCs
began to grow from early May and covers some 19 msqkm, a little
larger than the long term average. The bulk of the ozone layer
temperature is cooloing towards the -78°C Polar Stratospheric Clouds
(PSC) formation threshold and has passed it in the highest parts of
the ozone layer. The temperature of the ozone layer is now warmest
around Antarctica and declines towards the equator and the
pole. Ozone values are now building around the continent and lower
over it. They currently range from a low of around 240 Dobson Units
(DU) to a high of around 400 DU.
