Short summary

Quantifying greenhouse gas emissions from wetlands is vital for climate mitigation. Our high-precision measurements of CO₂, CH₄, and N₂O fluxes reveal highly dynamic exchanges, especially for CO₂ and N₂O, driven by temperature and groundwater fluctuations across hourly to monthly scales. These insights advance understanding of wetland emission regulation and support improved biogeochemical models.
