Addressing a systematic bias in carbon dioxide flux measurements with the EC150 and the IRGASON open-path gas analyzers

•CO2 flux measurement errors (IRGASON & EC150) scale with kinematic temperature flux.•Relative errors are most pronounced when true CO2 flux is small and heat flux large.•Using a fast-response air temperature to scale CO2 absorption minimizes bias.•Agreement between open- and closed-path IRGA CO...
