A11I:
Measurements and Modeling of Stable Isotopes to Advance Understanding of Non-CO2 Greenhouse Gas Cycling and Budgets Posters


Session ID#: 7362

Session Description:
The application of stable isotope techniques to resolve the origins and cycling of non-CO2 greenhouse gases is becoming more common. As a result, instrumentation and approaches for measurement and modelling of these gases are developing at a rapid rate, as demonstrated in particular by recent advances in spectroscopic techniques for isotope analysis. Non-CO2 greenhouse gases such as nitrous oxide, methane, and halocarbons are ideal targets for isotope methodologies due to their relatively long lifetimes and strong anthropogenic sources. However, a comprehensive understanding of complex non-CO2 greenhouse gas budgets and cycles requires synthesis of a number of disciplines, ranging from microbiology to atmospheric transport modelling.

This session aims to bring together scientists studying these gases using various isotopic techniques in different disciplines across a wide range of spatial and temporal scales, to assess the current state-of-the-art and promote exchange between disciplines into the future.
