| nitric acid |
A very soluble, acidic gas, formula HNO 3 , the end product of the oxidation of emitted gases. It is a major component of acidic precipitation in continental regions. In the clean background troposphere, its removal in precipitation acts as a sink for odd hydrogen and nitrogen compounds and limits the formation of ozone.

| nitric oxide |
A colorless gas, formula NO, the most common form of nitrogen emitted into the atmosphere, either by fuel combustion or due to natural emissions. Nitric oxide is interconverted with nitrogen dioxide fairly readily in the atmosphere, resulting in catalytic cycles leading to ozone formation in the troposphere and ozone loss in the stratosphere.

| nitrogen dioxide |
A brown gas, formula NO 2 , found at all levels in the atmosphere. In the troposphere it photodissociates to give free oxygen atoms, which then form ozone, and is thus a key player in local and regional air pollution events. In the stratosphere it participates in catalytic ozone destruction cycles, but also forms stable nitrate reservoir species that ameliorate ozone loss.

| nitrogen |
(Symbol N.) A colorless, tasteless, odorless gaseous element, atomic number 7, atomic weight 14.007. It is the most abundant constituent of the atmosphere, amounting to 78.09% by volume of dry air. The molecular formula for nitrogen gas is N 2 ; its molecular weight is 28.016. Nitrogen enters the atmosphere from volcanoes and from the decay of organic matter. It is removed from the atmosphere by certain natural nitrogen-fixing bacteria for use in plant life processes. ...

| nitrogen cycle |
A continuous series of natural processes by which nitrogen successively passes through air, soil, and organisms involving principally organism decay, nitrogen fixation, nitrification, and denitrification. See nitrogen-fixing plants.
