تعريف greenhouse gas في الإنجليزية الإنجليزية القاموس.
any gas, such as carbon dioxide or CFCs that contribute to the greenhouse effect when released into the atmosphere
Gases e g methane, carbon dioxide, CFC'c emitted from a variety of sources and processes, said to contribute to global warming by trapping heat between the earth and the atmosphere Methane produced at landfill sites is a major contributor
A gas, such as carbon dioxide or methane, which contributes to potential climate change
A greenhouse gas absorbs and radiates heat in the lower atmosphere that otherwise would be lost in space The greenhouse effect is essential for life on this planet since it keeps average global temperatures high enough to support plant and animal growth The main greenhouse gases are carbon dioxide (CO2), methane (CH4), chlorofluorocarbons (CFCs) and nitrous oxides (N20) By far the most abundant greenhouse gas is CO2, accounting for 70 percent of the greenhouse effect (see Carbon dioxide)
A gas that absorbs infrared radiation emitted by the Earth's surface and by clouds Water vapour (H2O), carbon dioxide (CO2), nitrous oxide (NO), methane (ÑH4) and ozone (O3) are the primary greenhouse gases in the Earth's atmosphere
Certain gases, such as water vapor, carbon dioxide, and methane, that more effectively trap heat affecting the Earth's surface temperature
A collective term for the gases that influence the greenhouse effect, ie the trapping of solar radiation by a layer of gases which heat up the Earth and lower atmosphere Estimates put carbon dioxide as the greatest contributor to global warming at around 50% The other main greenhouse gases include methane, chloroflurohydrocarbons (CFCs), ozone, water vapour and nitrogen oxides
Any of several dozen heat-trapping (radiatively active) trace gases in the earth's atmosphere which absorb infrared RADIATION The two major greenhouse gases are water vapor and CARBON DIOXIDE; lesser greenhouse gases include METHANE, ozone (O3), CFCs, and nitrogen oxides
Greenhouse gases are those gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of infrared radiation emitted by the Earth's surface, the atmosphere and clouds This property causes the greenhouse effect Water vapour (H2O), carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4) and ozone (O3) are the primary greenhouse gases in the Earth's atmosphere Moreover there are a number of entirely human-made greenhouse gases in the atmosphere, such as the halocarbons and other chlorine and bromine containing substances, dealt with under the Montreal Protocol Beside CO2, N2O and CH4, the Kyoto Protocol deals with the greenhouse gases sulphur hexafluoride (SF6), hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs)
A gas, such as water vapor, carbon dioxide, tropospheric ozone, methane, and low level ozone, which contributes to the greenhouse effect
gases in the atmosphere that absorb heat energy radiated from the Earth, trapping it in the atmosphere Important greenhouse gases include: water vapour, carbon dioxide, methane, nitrous oxide, ozone, and halocarbons
- A term given to those gas compounds in the atmosphere that reflect heat back toward earth rather than letting it escape freely into space Several gases are involved, including carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozone, water vapor and some of the chlorofluorocarbons Different gases have different reflective capacity, called Global Warming Potential (see above) In terms of the current atmospheric situation, it is estimated that CO2 is by far the most important contributor to climate change, causing some 80 percent of the impact according to the IPCC
Greenhouse gases are the gases which are responsible for causing the greenhouse effect. The main greenhouse gas is carbon dioxide. Any of the atmospheric gases that contribute to the greenhouse effect. a gas, especially carbon dioxide or methane, that is thought to trap heat above the Earth and cause the greenhouse effect
a gas in the atmosphere that has the ability to absorb infrared radiation (that emitted by the Earth itself), causing the same kind of action as a blanket or the glass windows of a greenhouse; includes water vapor, nitrous oxide, methane, carbon dioxide, ozone, halogenated fluorocarbons, hydrofluorocarbons, and perfluorinated carbons
Those gases that contribute to the greenhouse effect by trapping heat within the earth's atmosphere The chief greenhouse gases are carbon dioxide and water vapor Other potentially important trace gases are chlorofluorocarbons, methane, ozone, and nitrous oxide See Watson et al (1990) for a general overview and Ramanathan et al (1985) and Ramanathan et al (1987) for information on the trace gases
An atmospheric gas that tends to prevent heat from radiating back into space, thus having a warming effect on the atmosphere Examples: water vapor, carbon dioxide, methane
Any gas that absorbs infra-red radiation in the atmosphere Greenhouse gases include water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), halogenated fluorocarbons (HCFCs) , ozone (O3), perfluorinated carbons (PFCs), and hydrofluorocarbons (HFCs)
A gaseous component of the atmosphere contributing to the greenhouse effect Greenhouse gases are transparent to certain wavelengths of the sun's radiant energy, allowing them to penetrate deep into the atmosphere or all the way into the Earth's surface Greenhouse gases and clouds prevent some of infrared radiation from escaping, trapping the heat near the Earth's surface where it warms the lower atmosphere Alteration of this natural barrier of atmospheric gases can raise or lower the mean global temperature of the Earth
Is a gas that traps heat into the atmosphere The gas works in the same way as the glass in a greenhouse Heat energy enters the atmosphere, in a short wave-length form, however when the energy reflects off the earth it is in long wave form and so is trapped in the earths atmosphere
Gasses added to the atmosphere by human actions that trap heat and cause global warming
