Novel tracers in biosphere-atmosphere interactions
Convener: Alexander Knohl  | Co-Conveners: Matthias Cuntz , Matthias Zeeman 
Add this session to your Personal programme

Stable isotopes and other, novel tracers such as COS or clumped isotopes provide additional information on biogeochemical cycles at the soil-plant-atmosphere interface and help constraining ecosystem and atmospheric models at local to global scale. Current developments in analytical measurement techniques offer the opportunity to investigate these tracers in biosphere-atmosphere interactions at unprecedented temporal resolution and precision. This includes the stable isotopes in CO2, H2O, CH4, and N2O allowing to partition fluxes at the soil-plant-atmosphere interface, new tracers such as clumped isotopes, as well as COS as tracer of one-way fluxes. In this session we invite contributions that report latest instrumental development or contributions that give insight into biosphere-atmosphere interactions using tracers (natural abundance and label) at the soil-plant-atmosphere interface. Experimental and modeling approaches are welcomed.
