Atmosphere Interview Question:

Do you know that how much large depletion of the global ozone layer is in atmosphere?

Submitted by: Administrator

The ozone layer has been depleted gradually since 1980 and now is about an average of 4% lower over the globe. The average depletion exceeds the natural variability of the ozone layer. The ozone loss is very small near the equator and increases with latitude toward the poles. The larger polar depletion is primarily a result of the late winter/early spring ozone destruction that occurs there each year.
