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.
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
