The Tech Team is planning for the upcoming site visit season. If you would like to learn more about site visits and what to expect, please see our… More

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

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

Michael Benson, site manager at Morgan Monroe State Forest (US-MMS), notified the Tech Team of an important safety bulletin that affects many AmeriFlux tower workers. Some ladder safety system sleeves, model Lad-Saf, sold by Capitol Safety under the DBI-SALA brand are affected. Please view the full notice and contact the manufacturer if appropriate.  Thanks Michael!
