CO2, CH4, N2O, as well as 17 ozone CFC-11-eq, which is a radiative-efficiency weighted sum of all GHGs, except CO2, CH4, N2O and CFC-12: 'HFC-134a', 'HFC-23',

CO2 is the most important green-house gas, followed by N2O and CH4 in relative importance. 2011-03-01 · Photocatalysis looks like a panacea to fight all potent greenhouse gases, as photocatalyzed reactions are able to transform or destroy almost all well-mixed, long-lived greenhouse gases – CO 2, CH 4, N 2 O, CFC-12 and CFC-11 – which account for about 96% of the direct radiative forcing, and also short-lived climate forcers like VOCs, NOx, BC and soot that have an important contribution to climate change. LLGHGs (CO 2, CH 4, N2O, CFC-12 and CFC-11) account for about 96% of the direct radiative forcing since 1750. In table 1 the main characteristics of LLGHGs are listed in terms of Global Radiative Forcing in W.m-2, Global Warming Potential GWP 100 (time horizon of 100 years), Atmospheric lifetimes in years and relative importance in %. 2012-01-16 · Aside from water vapour, the four principal greenhouse gasesare carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and the halocarbons or CFCs (gases containing fluorine, chlorine and Year Month MEI CO2 CH4 N2O CFC-11 1983 5 2.556 345.96 1638.59 303.677 191.324 1983 6 2.167 345.52 1633.71 303.746 192.057 1983 7 1.741 344.15 1633.22 303.795 192.818 1983 8 1.13 342.25 1631.35 303.839 193.602 1983 9 0.428 340.17 1648.4 303.901 194.392 1983 10 0.002 340.3 1663.79 303.97 195.171 1983 11-0.176 341.53 1658.23 304.032 195.921 1983 12-0.176 343.07 1654.31 304.082 196.609 1984 1-0.339 344.05 1658.98 304.13 197.219 1984 2-0.565 344.77 1656.48 304.194 197.759 1984 3 0.131 345.46 1655 84 x – methane (CH 4) – I.e. Releasing 1 kg of CH4 into the atmosphere is about equivalent to releasing 84 kg of CO 2. Methane’s 100-year GWP is about 28x CO2 – but it only persists in the atmosphere for a little more than a decade. The 100-year GWP is used to derive CO 2 e.

Carbon dioxide equivalent is calculated from GWP. It can be measured in weight or concentration. For any amount of any gas, it is the amount of CO 2 which would warm the earth as much as that amount of that gas. Thus it provides a Los gases de efecto invernadero como el dióxido de carbono (CO2), el metano (CH4) y el óxido nitroso (N2O) tienen la capacidad de cambiar la temperatura de la Tierra. Su medición proporciona información importante acerca de las emisiones de gases de efecto invernadero y los permisos para el control y la comprensión de los cambios climáticos. 2016-04-20 · The four greenhouse gases with the strongest effect on climate through their climate forcing are water vapor (H 2 O), carbon dioxide (CO 2), methane (CH 4), and nitrous oxide (N 2 O) (I’m omitting halocarbons, which come in a wide variety). We don’t control the concentration of water vapor, temperature does that.
