Every austral spring, an ominous "hole" appears in stratospheric ozone over Antarctica.
Data processing and analyses show that photon overlap effect greatly on lower stratospheric ozone measurements.
Nitrous oxide (N2O) is a trace gas in the atmosphere, which contributes both to the greenhouse effect and to the destruction of stratospheric ozone.
Nitrous oxide exists at low levels in the atmosphere, yet is thought to be responsible for 6 percent of climate warming and also contributes to stratospheric ozone destruction.
