Atmospheric sciences

In atmospheric chemistry:

• [[NOx|Template:Chem2]] (or NOx) refers to the sum of NO and [[nitrogen dioxide|Template:Chem2]].<ref>United States Clean Air Act, Template:USC</ref><ref>

• [[NOy|Template:Chem2]] (or NOy) refers to the sum of Template:Chem2 and all oxidized atmospheric odd-nitrogen species (e.g. the sum of Template:Chem2, [[Nitric acid|Template:Chem2]], [[Nitrous acid|Template:Chem2]], etc.)
• Template:Chem2 (or NOz) = Template:Chem2 − Template:Chem2

• Mixed Oxides of Nitrogen ("MON"): solutions of nitric oxide in dinitrogen tetroxide/nitrogen dioxide.

Stability

Due to relatively weak N–O bonding, all nitrogen oxides are unstable with respect to Template:Chem2 and Template:Chem2, which is the principle behind the catalytic converter, and prevents the oxygen and nitrogen in the atmosphere from combusting.
