Manuscript evaluating a suite of flux-gradient methods for determining ecosystem H2 fluxes

A manuscript I’ve been working on entitled “Ecosystem fluxes of hydrogen: a comparison of flux-gradient methods,” was now been published in Atmospheric Measurement Techniques (view paper online). Our goal was to present a detailed experimental approach for measuring ecosystem fluxes of H₂ and to test different so-called “flux-gradient methods” for calculating the H₂ fluxes. Some common trace gas flux methods, e.g. eddy covariance, are not available for species like H₂ that cannot be measured precisely at high frequencies (<1 Hz). We hope this paper will help inform the design of future studies for which flux-gradient methods might be the best option for measuring trace gas fluxes.

Here are a couple videos on the instrument deployment and design for more information.
