       TIL, Ozone layer is just 3mm thick. About two coins stacked together.https://ozonewatch.gsfc.nasa.gov/facts/dobson_SH.html#til #todayilearnedhttps://www.reddit.com/r/todayilearned/comments/18khj9g/til_ozone_layer_is_just_3mm_thick_about_two_coins/

       @todayilearned "Ozone in the atmosphere isn’t all packed into a single layer at a certain altitude above the Earth’s surface; it’s dispersed. [...] Satellite sensors and other ozone-measuring devices measure the total ozone concentration for an entire column of the atmosphere. The Dobson Unit is a way to describe how much ozone there would be in the column if it were all squeezed into a single layer."
