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

Over the past decades, the eddy covariance (EC) community has clearly demonstrated the power of networks; regional networks and FLUXNET have shown us that combining data across multiple sites creates a whole that is greater than the sum of its parts. The FLUXNET database has been used extensively to evaluate satellite measurements, inform Earth system… More

This year, the AmeriFlux Annual Meeting and Early Career Workshop are being held on Tuesday, September 17th – Thursday, September 19th, 2019 in Boulder, Colorado, at the Millennium Harvest House Hotel. In a break from previous years, we have decided to hold the AmeriFlux Data/Tech Workshop separately and, with a new focus on inclusivity and… More

North of Boston lies the Great Marsh, the largest remaining complex of salt marshes in New England. Here, the Plum Island Ecosystems LTER is studying long-term changes in coastal ecosystems, particularly those due to an acceleration in sea level rise. In contrast to most southern marshes, the Great Marsh is currently dominated by Spartina patens… More

Tucked away on the remote Seward Peninsula in the far west of Alaska lays the Arctic outpost for the Department of Energy’s Next Generation Ecosystem Experiment (NGEE-Arctic) and its associated AmeriFlux site (US-NGC). During the summer months each year, when US-NGC is accessible by road, blueberries fruit across the surrounding tundra and river valleys, attracting… 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

Until recently it was assumed that all exchange of methane between forests and the atmosphere takes place at the soil surface, and can be captured by an understory eddy covariance (EC) system. Based on a comprehensive review just published in New Phytologist, it is now clear that all surfaces in a forest—living wood, dead wood,… More

While many people in the AmeriFlux community may be familiar with rice and methane emissions, most are usually surprised by the connection rice has to the state of Arkansas, which accounts for about half of U.S. rice production. Rice fields in Arkansas are concentrated in the eastern part of the state on the Mississippi River’s… More
