Abstract: Precise and rapid analyses of greenhouse gases (GHGs) will advance understanding of the net climatic forcing of coastal marsh ecosystems. We examined the ability of a cavity ring down spectroscopy (CRDS) analyzer (Model G2508, Picarro) to measure carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) fluxes in real‐time from coastal marshes through comparisons with a Shimadzu GC‐2014 (GC) in a marsh mesocosm experiment and with a similar laser‐based N2O analyzer (Model N2O/CO, Los Gatos Research) in both mesocosm and field experiments.
