Society is facing several crucial issues involving atmospheric chemistry, Species containing nitrogen are major players in each. In the troposphere, nitrogen species are catalysts in the photochemical cycles that form ozone, a major urban and rural pollutant, as well as other oxidants (references 1 and 2, and references cited therein), and they are involved in acid precipitation, both as one of the two major acids (nitric acid) and as a base (ammonia) (3, 4). In the stratosphere, where ozone acts as a shield for the... 

Li, and Cal profiles ai altitudes of Xrt to I00 km. The method also has been useful lor studying ihe hydroxyl free radical (OH), This radical is of principal inlerest because or ihe cataly tic role which it exerts in atmospheric chemistry. The OH radical, along with chlorine and nitrogen oxides, is involved in the ozone destruction cycle. 

Nitric oxide (NO), nitrous oxide (N2O), dinitrogen (N2), and ammonia (NH3) are constituents of the Earth s atmosphere. They play important roles in the chemistry and climate of the present-day Earth. Moreover, they are intermediates of the oceanic nitrogen cycle. In contrast to most of the other components of the oceanic nitrogen cycle, they exist as dissolved gaseous molecules. Being gases they can be transferred across the seasurface-troposphere interface. 

Kinetics is being employed increasingly to study the soil chemistry of carbon, nitrogen, potassium, phosphate, and trace metals. The soil reactions of these elements are often slow enough to be experimentally measurable. Because carbon and nitrogen cycle back and forth between soil, water, plants, animals, and atmosphere faster than...

One of the most important ways of relating the environmental chemistry of the five environmental spheres is through biogeochemical cycles. These are commonly expressed in terms of key elements, including essential nutrient elements. Often, as is the case with the nitrogen cycle, they contain an atmospheric component, though in some cases, such as the phosphorous cycle, the atmospheric component is not significant. Before the appearance of humans on Earth, the anthrospheric...
