Old Value=Water present in the atmosphere in gaseous form; the source of all forms of
condensation and precipitation. Water vapor, clouds, and carbon dioxide are the
main atmospheric components in the exchange of terrestrial radiation in the
troposphere, serving as a regulator of planetary temperatures via the
greenhouse effect. Approximately 50 percent of the atmosphere's moisture lies
within about 1.84 km of the earth's surface, and only a minute fraction of the
total occurs above the tropopause.
New Value=Water substance in vapor form; one of the most important of all constituents of the atmosphere.
