on that topic - where does the O³ come from?![](https://discuss.tchncs.de/pictrs/image/37d8b46d-52e4-4e63-b6c0-646962750dc7.png)
a fellow breezy weather user!
you can tap on it to read more about it.
I also use this app! It’s great, isn’t it?? ^_^
Is that screenshot from the main app or a widget? Because my app looks bright even in dark mode.
Turn off the “follow day/night” setting and it will be dark mode in the day as well
Ah apparently, it is more common to occur naturally in the countyside because the NOx from fossil fuels will react with the ozon to create NO² and O².
I think the O3 ozone is a byproduct of combustion at high temperatures and not ideal combustion ratios. But I don’t know a whole lot about it.
Ozone if formed usually when UV rays hit Oxygen(O2), and if forms protective ozone layer high up in atmosphere. But ground level ozone like this are formed from other pollutants in the presence of sunlight. That is factory and vehicle’s pollutants react on sunlight and creates ozone which is harmful
