fluxible: An R package to process ecosystem gas fluxes from closed‐loop chambers in an automated and reproducible way

Le résumé fourni par la source

Abstract Measuring ecosystem gas fluxes is crucial to understanding the dynamics of ecosystem water and energy cycling. A common method to measure ecosystem gas fluxes (CO 2 , CH 4 , N 2 O) and to compare experimental treatments is the use of closed‐loop chambers. However, the output data require extensive processing before analysis, making the workflow prone to bias and limiting comparability between studies. While there are various methods to process flux data, they lack reproducibility and automation. The fluxible R package provides a reproducible way to process raw gas concentration data from closed‐loop chambers into an analysis‐ready dataset of ecosystem gas fluxes. The processing steps include (1) separating the measurements, (2) fitting a linear, quadratic, or exponential model, (3) assessing the quality of the fit, (4) plotting the fluxes for visual inspection and (5) calculating the fluxes. In addition to reproducibility, fluxible focuses on homogeneity and automation in data processing, thus reducing the time investment for users while improving comparability across studies.
