qN2O is currently the largest
source of stratospheric odd nitrogen (NO and NO2).
q
qHow human
activity affect NO?
q high-flying, supersonic transport
airplanes
q è Jet plane-produced high
temperatures from combustion.
q è combine N2 and O2 to form
NO.
q è injected NO goes to the
stratosphere and destroy ozone
q è This is why jet plans can
affect stratospheric ozone layer
q (even though jet plans fly in the upper troposphere).
