Data for leaf photosynthesis and net ecosystem exchange of CO2 and CH4 from wetland forest, marsh, and mudflats under simulated ambient and elevated atmospheric carbon dioxide (2013-2014)

This study evaluated the net ecosystem exchange of CO2 and CH4 from experimental wetland mesocosms established in elevated CO2 and ambient CO2 glasshouses at the U.S. Geological Survey’s Wetland and Aquatic Research Center (Lafayette, Louisiana). The study duration was approximately two years, and these data represent measured and calculated data from four time points, which the investigators associate with season.
