This is a research program in a northern peatland ecosystem to improve the understanding of surface fluxes of methane. Included in the program are the measurement and analysis of "really-integrated" methane fluxes, the characterization of pertinent environmental factors that control methane emission, and modeling to estimate annual methane emissions from major peatland types in the northern hemisphere. Our experimental approach will utilize micrometeorological eddy correlation techniques, employing tunable diode laser spectroscopy (TDLS), for measuring surface fluxes of methane. Conventional chamber methods will also be used to provide supporting information.

这是北部泥炭地生态系统中的一个研究项目，旨在提高对甲烷表面通量的理解。该计划包括“真正整合的”甲烷通量的测量和分析，控制甲烷排放的相关环境因素的表征，以及估计北半球主要泥炭地类型的年度甲烷排放量的模型。我们的实验方法将利用微气象涡旋相关技术，使用可调谐半导体激光光谱(TDLS)来测量甲烷的表面通量。也将使用传统的内庭方法来提供支持信息。
