The sun does that naturally.
No. The ozone layer is self healing, once the megatons of Manmade chemicals are removed from the upper atmosphere. Lofting any sort of "band-aid" solution will cause more damage than the chemicals are currently doing... even water vapor depletes ozone and fuel combustion produces water vapor. The solutions require time: restore forests, reduce high altitude flights, stop using extremely stable chlorine- and bromine-containing compounds without recovery, reclaim ozone destroying compounds from the air.
There are various ways of measuring ozone. One is ozone balloons.
Actually the ozone layer is good.
Ozone is harmful at ground level. It acts as a pollutant.
Ozone is found in the air. By the way, I don't think there is such thing as good ozone.
The time it takes depends on us. The appropriate level can be reached if we stop CFC's.
The hole in the ozone layer is caused by both natural and man made factors. The UV rays are the natural way of ozone destruction while the use of CFC is the man made way of depleting ozone.
You do not want to overcome ozone layer. It is vital for life on earth.
Mobile in some way do not harm ozone. The preparation maybe can.
Grounded the Concorde.Banned the use of compounds known to cause ozone depletion in the conditions in the ozone layer.
It is next to impossible thing to have no ozone in the atmosphere. Large solar mass ejections could cause some thinning of the ozone layer equal to, or greater than the worst thinning we are aware of (1859 sme event). Should this happen though, the sun's uv rays would react with the oxygen in our atmosphere and restore the ozone in short order. As long as we have oxygen and sunlight to react with it, we will have ozone.
Ozone layer affect the aersols. Actually it is the other way around.
