Soil acts a source and sink of multiple greenhouse gases (including CO2, CH4 and N2O) and biogenic volatile organic compounds (BVOC) and nitrous acid (HONO) which are important precursors of atmospheric chemistry. Understanding on the processes underlying the production and consumption of these gases is a pre-supposition for improving the estimations of the gas fluxes between soil and the atmosphere. This session will focus on measurements of soil gas concentrations and modelling the gas transport in soils to help to understand the temporal and spatial variability of their production and consumption in soils.

The session is also targeted for studies using stable or radioactive isotopes in understanding the transport processes of greenhouse and reactive gases in soils. We also welcome all other innovative approaches for soil gas sampling, measurements and modelling.
