Technical Abstract: Micrometeorological methods for measuring carbon dioxide and nitrous oxide provide an opportunity for large-scale, long-term monitoring of greenhouse gas flux without the limitations imposed by chamber methods. Flux gradient and eddy covariance methods have been used for several decades to monitor greenhouse gases and large international networks now exist to coordinate efforts to understand environmental and management effects on carbon dioxide flux. Less information is available on nitrous oxide flux and an expanded effort to provide year-round assessment of this important greenhouse gas is needed. This chapter provides an overview of common micrometeorological methods used for flux measurements, discusses benefits and shortcomings of these methods, outlines corrections and adjustments to the raw data that are needed to obtain meaningful measurements and fill gaps in the data, and provides examples of unique insights into mechanisms that control greenhouse gas fluxes that can be obtained through micrometeorological methods.
