HS8.3.5Trace gases emissions from soils: Sources, mechanisms and process rates
|Convener: Lutz Weihermueller | Co-Convener: Yakov Kuzyakov|
Greenhouse gas emissions (CO2, N2O and CH4) from natural and agricultural soils still pose a challenge for scientists. Despite their importance for global warming and atmospheric chemistry, the process understanding is limited which hampers our ability to estimate emissions for larger scales, predict emissions for future conditions or evaluate potential reduction scenarios.
Important uncertainties remain among others on the effect of heterogeneities on various scales, the balance and interaction between production and uptake in the soil profile, and/or the effect of changing conditions on greenhouse gas production and emission.
This session seeks to bring together both experimentalists and modellers from various communities, to increase our common understanding about greenhouse gas emissions from soils. We welcome contributions from studies at all scales, ranging from controlled lab experiments, field studies to model studies.
