q |
N2O is currently the largest source of stratospheric odd
nitrogen (NO and
|
|
NO2).
|
|
|
q |
How human activity affect NO?
|
|
|
high-flying, supersonic transport airplanes
|
|
|
è Jet plane-produced high temperatures from combustion.
|
|
|
è combine N2 and O2 to form NO.
|
|
|
è injected NO goes to the stratosphere and destroy ozone
|
|
|
è This is why jet plans can affect stratospheric ozone
layer
|
|
|
(even though jet
plans fly in the upper troposphere).
