For Water vapor we have terms and definitions in 9 topics. The topics are Atmospheric Chemistry, Boiler, Climate, Climatology, Energy, Global Warming, Hydrology, Roofing and Science.

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.
