Potential Ozone Depletion From Satellite Demise

Potential Ozone Depletion From Satellite Demise During Atmospheric Reentry in the Era of Mega-Constellations

Interesting paper that was published in Geophysical research letters looking at potential damage to the Ozone layer from Satellites re-entering the Earths atmosphere and burning up. The specific issue seems to be related to the Aluminium Oxidizing, and then this travels down to the Ozone layer and causes a chemical reaction.

Give the number of Satellites in orbit and the importance of the Already fragile Ozone layer, this is not good news.

You can read the research here

There is a Fediverse discussion here that is quite interesting, I have also started a Science Forums discussion

Volcanoes and Ozone

This was posted to the fediverse after I asked how the ozone layer is being further depleted despite the world wide ban on CFCs and similar chemicals. It turns out that a volcano can throw out chemicals that can react and reduce Ozone (O_3) in the atmosphere.

• Tonga's eruption injected so much water into Earth’s atmosphere that it could weaken the ozone layer
