Residence time of gases in the atmosphere

WebWhat is residence time of greenhouse gases? Residence time is the average time it takes for a molecule to be removed, so in this case for every molecule of methane that goes into the atmosphere it stays there for 8 years until it is removed by some process. Which pollutant has the longest residence time? Nitrous oxide has a long residence time ... The overall abundance of man-made trace gases in Earth's atmosphere is growing. Most originate from industrial activity in the more populated northern hemisphere. Time-series data from measurement stations around the world indicate that it typically takes 1-2 years for their concentrations to become well-mixed throughout the troposphere. The residence time of a trace gas depends on the abundance and rate of removal. The Junge (em…
