On behalf of co-authors Sara Knox, Rob Jackson, and Ben Poulter Inviting the entire flux community to participate! Take the survey. As part of a recent Global Carbon Project methane budget activity funded by the Moore Foundation, we are organizing the collection and aggregation of global CH4 data from the flux tower community in coordination with… More

Again we’re collecting AGU Fall 2018 sessions we think will interest our AmeriFlux Community members.  Right now I’m assembling those where you might want to submit an abstract. The AGU Fall 2018 abstract submission portal is open now; deadline is August 1 (early submission is July 25). Tell me know if you’d like yours added… More

  We are conducting  a pilot study to evaluate methods for the estimations of aerodynamic roughness parameters (i.e., roughness length (z0), zero plane displacement height (d)) from single-level eddy covariance measurements. Results will guide development for future AmeriFlux and FLUXNET datasets.  Thanks to the flux community, most required variables are available through the AmeriFlux database (e.g., wind speed (WS),… More

At one of the NGEE Arctic sites in the Seward Peninsula, near the town of Council, Alaska, the Dream Team—myself, Oriana Chafe, Margaret Torn (NG Arctic team lead), Stan Wullschleger (NG Arctic PI), Mark Conrad, Bryan Curtis and Sigrid Dengel (AMP) (see photo, left to right)—is flying a DGI model Inspire-1 UAS (unmanned aircraft system, or drone)….

The 8th Colorado Flux Course (#fluxcourse; http://www.fluxcourse.org/) was recently convened up at Niwot Ridge, Colorado. Twenty-five students from across the US and globe came to hear lectures on eddy covariance, flux instrumentation, leaf cuvette systems, land surface modeling, remote sensing and data fusion modeling.  Students also toured the Niwot Ridge AmeriFlux site (US-NR1) and visited NEON….

Evapotranspiration based on equilibrated relative humidity (ETRHEQ): Evaluation over the continental U.S. From Water Resources Research 51(4),2951-2973, 2015. DOI: 10.1002/2014WR016072. Copyright (2015) American Geophysical Union. Guido Salvucci’s group at Boston University are avid users of AmeriFlux data. There is a new paper in Water Resources Research that explores a way to estimate watershed scale evaporation…. More
