Understanding the Influences of Seasonality and Interannual Variability on Biosphere-Atmosphere 13CO2 Exchange in a Network of Eight AmeriFlux Sites

Whole-air samples have been collected on weekly intervals since 2001. Air samples are analyzed for concentrations and stable isotope composition of atmospheric CO2, which are linked with net ecosystem exchange measurements to investigate variations of carbon fluxes in diverse ecosystems across the USA.
