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 ameriflux-support@lbl.gov. 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 ameriflux-support@lbl.gov), or visit 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

The Joint AmeriFlux-NACP PI Meeting is next week—March 27–30, in North Bethesda MD.

(1) Tuesday evening 3/28 , 7pm, room White Oak A: The AmeriFlux Community Meeting. We have a packed agenda that includes… More

From our guest author, Dario Papale I’m happy to announce in name of the whole FLUXNET2015 Team that the new and last update of the FLUXNET2015 dataset has been released. To download, go to: http://fluxnet.fluxdata.org You will find also the list of changes in respect to the previous version, in particular, the 47 new sites and… More

I am pleased to announce the AmeriFlux 20th Anniversary Special Issue in the journal Agricultural and Forest Meteorology. Manuscripts are solicited from across the broad spectrum of research using flux data or flux sites. We are particularly interested in studies that examine linkages among ecosystem processes and the environment, test innovative observational and analytical approaches, or… More
