greenhouse gases

[′grēn‚hau̇s ‚gas·əz]
(meteorology)
Gases whose concentration is small and varies, mostly due to anthropogenic factors; they absorb heat from incoming solar radiation but do not allow long-wave radiation to reflect back into space. They include carbon dioxide, methane, and nitrous oxide, as well as, water vapor, carbon monoxide, nitrogen oxide, nitrogen dioxide, and ozone.
