Forest Soil-Atmosphere Interface Greenhouse Gas Flux Monitoring Solution

Forest ecosystems play a crucial role in the global carbon and nitrogen cycles. Through photosynthesis, CO₂ is sequestered from the atmosphere into plants and then released back into the atmosphere through respiration and the decomposition of organic matter by soil microbes. In soil, N₂O is produced and released into the atmosphere via microbial nitrification and denitrification, processes that reflect the transformation of nitrogen from organic to inorganic forms and its cycling between different states. Both CO₂ and N₂O are significant greenhouse gases. Carbon dioxide, as one of the primary greenhouse gases, requires long-term dynamic monitoring to assess the forest’s function as a carbon sink. Although nitrous oxide is present in lower atmospheric concentrations, its high global warming potential (GWP) means it contributes more significantly to climate change. Therefore, precise monitoring of CO₂ and N₂O fluxes in forests is critical for understanding the role of forest ecosystems in the carbon and nitrogen cycles, evaluating their impact on climate change, and optimizing carbon management and greenhouse gas mitigation strategies as we pursue global "carbon neutrality."
