WP3.2: CH₄ and N₂O cycle

WP3.2 objectives

• To characterize at high resolution the slow and fast variations in the atmospheric content and isotopic signature of CH₄ and N₂O during warm periods, i.e. the present and the last interglacial.
• To better constrain biogeochemical mechanisms responsible for the production of the greenhouse gases CH₄ and N₂O through data-model integration.
• To obtain a better understanding of the biogeochemical mechanisms controlling feedbacks between climate and methane and nitrous oxide sources.
