Atmospheric Composition and Greenhouse Gases Quiz

CO2 = Efficient greenhouse gas, absorbs 60% IR radiation emitted by earth surface H2O = Source of clouds and precipitation O3 = Good in stratosphere and bad in troposphere GWP index = Metric indicating the contribution of a substance to global warming in comparison to CO2

CO2 = One third in the atmosphere after used up by plants and absorbed by ocean H2O = 4% in the atmosphere O3 = 10% in troposphere and 90% in stratosphere GWP index = An index based on radiative properties of greenhouse gases measuring the radiative forcing following a pulse emission of a unit mass

Global Warming Potential (GWP) index = Introduced to put the contribution of all the non-CO2 GHGs gases to the climate change over the normalized CO2 scale Radiative forcing = Measure of the strength of the greenhouse effect Greenhouse gases = Substances that trap heat in the atmosphere Pulse emission = Emission of a unit mass of a given greenhouse gas in the present day atmosphere integrated over a chosen time horizon

<p>CO2 = Burning of fossil fuels such as coal and oil H2O = N/A O3 = N/A GWP index = Intergovernmental Panel on Climate Change, 2013</p> Signup and view all the answers

<p>CO2 acts as an efficient greenhouse gas, absorbing 60% of IR radiation emitted by the Earth's surface. It is sourced from the burning of fossil fuels such as coal and oil.</p> Signup and view all the answers

<p>The GWP index measures the contribution of a substance to global warming in comparison to that of CO2. It is calculated based on the radiative forcing following a pulse emission of a unit mass of a given greenhouse gas in the present-day atmosphere integrated over a chosen time horizon, relative.</p> Signup and view all the answers
