We have started a list of AGU Fall 2017 sessions that AmeriFlux community members may want to check out. Please send us any sessions that you think we should add to this list.  The AmeriFlux Townhall is Tuesday, December 12, at 12:30pm in Rooms 255-257. Hope to see you in New Orleans! 12/11 08:00-10:00 GC11E… More

The AmeriFlux Tech Team has completed another successful site visit season. This year they visited six AmeriFlux sites. The team also deployed the portable profile system at two sites. Here are a few images from the site visits. The Tech Team is planning for the 2018 site visit season. If you would like to learn more… More

Henry Gholz died tragically in a mountain climbing accident September 30, 2017, in Rocky Mountain National Park.  Henry earned B.S. and Ph.D. degrees from Oregon State University, and was a faculty member specializing in forest ecosystems ecology in the School of Forest Resources and Conservation at the University of Florida from 1979 until 2000.  In… More

Prof.  Gaby Katul, PI of the Duke Forest Ameriflux sites and Professor at Duke, was awarded the Dalton Medal in Hydrological Sciences by the European Geophysical Union.  Congratulations.

The AmeriFlux portable profile system (PPS) was built to understand and improve how storage is being measured as a complimentary activity to site visits by the Tech Team.

Margaret Torn is among this year’s class of scientists who have been elected Fellow of the American Geophysical Union.  Only 0.1% of the membership is elected each year and are elected on the basis of breakthroughs, innovations and sustained excellence in science and research. Congratulations! 2017 Class of AGU Fellows Announced

We are happy to announce that Prof. Jose Fuentes of Penn State, is the 2018 recipient of the American Meteorology Award for OUTSTANDING ACHIEVEMENT IN BIOMETEOROLOGY. ‘For uncovering the significance and workings of key interactions among flora, fauna, and the atmosphere and their role in regional and global environmental change.’ Congratulations, Jose.

The previous AmeriFlux Tech blog post regarding biases in CO2 flux measurements contributed by Manuel Helbig generated some questions from the community.  Campbell Scientific provided a detailed response to address the questions. The response describes the new gas analyzer operating system that accounts for the spectroscopic effects using high frequency sonic temperature. The response also includes a methodology… More

The AmeriFlux Management Project has a new tracking system for e-mail sent to The tracker monitors support requests and their resolutions. It also monitors Data QA/QC using the system. To check status on your pending requests, click on the ‘View request’ link in our response e-mail (these will come from, or visit the AmeriFlux… More

A reminder that June 9, 2017, midnight EDT, is the deadline to submit your article for the Special AmeriFlux 20th Anniversary Issue in Agricultural and Forest Meteorology. Guest Editors are Ken Davis, Trevor Keenan, Kim Novick, and Margaret Torn. Visit this page to submit. To make sure that Ag and Forest Met routes your submission to the AmeriFlux… More

Updated May 24, 2017 to include response from Campbell Scientific (see bottom of post).  Across FLUXNET, CO2 fluxes between ecosystems and the atmosphere are measured using various open- and closed-path gas analyzers. A few years ago, Campbell Scientific introduced new open-path CO2/H2O gas analyzers (IRGA; EC150 and IRGASON), thus, further diversifying the choices for eddy covariance… More
