Manuscript published on flux-gradient methods for ecosystem H2 flux measurements

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.

Deployment day!

Two years after embarking on my thesis project to design and build a custom instrument that measures hydrogen fluxes, I deploy my creation to the Harvard Forest Long Term Ecological Research site in Petersham, Massachusetts. The instrument shed is tight, but with the help of colleagues at Harvard University, the move is successful. In this short documentary by co-student Ryan Abernathey we introduce the forest and the project, but the work has only just begun…
