Description
This fellowship opportunity, offered through the NRC Research Associateship Programs in partnership with NOAA's Global Monitoring Laboratory, supports research on modeling sources and sinks of atmospheric trace gases using observed mixing ratios. The project focuses on anthropogenic trace gases such as nitrous oxide, chlorofluorocarbons, halons, hydrochlorofluorocarbons, hydrofluorocarbons, sulfur hexafluoride, and perfluorocarbons measured worldwide.
The research employs inverse modeling techniques to estimate emissions and sinks, helping to verify compliance with international agreements like the Montreal Protocol aimed at reducing greenhouse gases and ozone-depleting substances. The models also enable determination of key atmospheric parameters, such as the global distribution of hydroxyl radicals (OH), which act as natural atmospheric cleansers by removing pollutants.
NOAA scientists measure trace gases produced by both anthropogenic and natural processes at global monitoring sites. Some gases have significant oceanic sinks, and the research aims to quantify the strengths of these sources and sinks to inform policymakers on strategies to reduce harmful global emissions.
