A brown gas, formula NO<sub>2</sub>, 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.

1. Weak acid formed in solution by neutralization of the nitrite ion. Also formed when nitrogen dioxide, NO<sub>2</sub>, dissolves in water. 2. Gaseous compound, formula HONO, that builds up in polluted, typically urban air, containing nitrogen oxides. The only known gas-phase reaction leading to its formation, that between hydroxyl radicals (OH) and nitric oxide (NO), is not rapid enough to account for observed levels, and the formation is thus thought to involve particles. Nitrous acid photodissociates to give OH + NO, and can thus serve as an OH source, particularly in the early morning.
Industry:Weather
The preferred system for measuring most quantities in scientific disciplines.
Industry:Weather
The speed of propagation of a mathematical surface of constant phase (or phase angle) of a time-harmonic wave. Compare group velocity.
Industry:Weather
A chart showing, principally, the expected pressure pattern (or height pattern) of a given synoptic chart at a specified future time. Usually, positions of fronts are also included, and the forecast values of other meteorological elements may be superimposed.
Industry:Weather
A point of maximum decrease in atmospheric pressure over a specified interval of time; on synoptic charts, a point of greatest negative pressure tendency; opposed to a pressure- rise center.
Industry:Weather
The round-trip time for a radar pulse to travel out and back to a target one statute mile away, or 10. 75 μs.
