The soil-to-atmosphere CO2 flux – or soil respiration – is one of the largest carbon fluxes in the earth system. An increasing number of continuous measurements have been made over the last 25 years; these data are an invaluable resource for probing the sensitivities of respiration and the carbon cycle more generally. AmeriFlux is excited… More

The AmeriFlux Data Team will solicit feedback about Format QA/QC automation described in this post at the annual AmeriFlux meeting… More

The inhibition of leaf respiration in the light has long been reported at a leaf scale, but recent isotopic evidence suggests that inhibition also occurs at the ecosystem scale. This is important, as inhibition at the ecosystem scale would imply a significant bias in current estimates of ecosystem photosynthesis and respiration, but it is not known… More
