The ‘amerifluxr’ [pronounced: uh-merr-ee-fluhks-arrr] — an R package that allows querying, downloading, and handling AmeriFlux data and metadata — is now released through the CRAN repository. The package was developed by Housen Chu and Koen Huffkens, with support from the AmeriFlux Management Project. The target users include those who intend to use data from many… More

AmeriFlux principal investigators are quickly adopting the new AmeriFlux CC-BY-4.0 Data License, which allows their sites’ AmeriFlux data to be shared under the widely-used Creative Commons BY 4.0 license (CC-BY-4.0). This license allows data use as long as attribution is provided. This new license is more open than the historical AmeriFlux data policy, which is… More

Dec 7-8 2019 The Coastal Carbon Research Coordination Network (CCRCN) held its second working group workshop this past December at NASA’s AMES Research Center in Mountain View, CA hosted by the US Geological Survey. This year’s working group is focused on improving predictions of methane emissions from coastal wetlands. Specifically, we aim to compile all… More

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

AmeriFlux showcased the Year of Methane action year at the 2019 Annual Meeting with an oral session, methane posters, and three methane breakout discussions. Ruminants, Forests, and Wetland Management The Year of Methane talks illustrated the variety of new directions enabled by methane flux measurement. Dave Hollinger, a Forest Service research scientist, gave the invited… More

The AmeriFlux Site Search webpage has been updated to improve the data user experience. It’s now possible to search the 250-plus AmeriFlux sites with flux-met data by data variable and by year. All 460-plus sites can be searched by affiliated network. The new site search capabilities are the latest in a series of enhancements to… More

Flux-met data Format QA/QC is fully automated. Instead of receiving feedback within a business day, uploaders will now receive Format QA/QC results shortly after uploading flux-met data on the AmeriFlux website. Keep the feedback coming! 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
