stratosphere is the layer which is polluted by supersonic jets and is present in the atmosphere. Proposed supersonic airplane will fly in the stratosphere close to 20 km, where stratospheric habitation times because of trade with the troposphere increment to years. In the upper troposphere, increments in NOx commonly lead to increments in ozone.
Ozone consumption comprises of two related occasions saw since the late 1970s: a consistent bringing down of around four percent in the aggregate sum of ozone in Earth's air (the ozone layer). These have both characteristic and man-made sources; at present, a large portion of the OH· and NO· in the stratosphere is normally happening.
This is one of the serious atmosphere related developments in the recent times of Science world.
