Parsing, Computation, and Diagnostics for Greenhouse Gas Measurements

Parse static-chamber greenhouse gas measurement files generated by a variety of instruments; compute flux rates using multi-observation metadata; and generate diagnostic metrics and plots. Designed to be easy to integrate into reproducible scientific workflows.

fluxfinder

The goal of fluxfinder is to allow users to straightforwardly parse data files generated by infrared gas analyzers used in environmental sciences research; match data and metadata; compute greenhouse gas fluxes; and generate QA/QC plots and diagnostics.

We emphasize clear and well-documented code, good documentation, and focused functions that can be easily integrated into conventional or tidyverse-style analytical pipelines.

It is also straightforward to integrate this package's utilities with the more powerful flux-computation capabilities of the gasfluxes package.

Installation

You can install fluxfinder from CRAN...

install.packages("fluxfinder")

...or the development version of fluxfinder from GitHub with:

# install.packages("remotes")
remotes::install_github("COMPASS-DOE/fluxfinder", build_vignettes = TRUE)

Supported data file types

Currently fluxfinder provides functions to read data from:

• The LI-COR Smart Chamber
• LI-COR 78xx Trace Gas Analyzers, including the LI-7810 and LI-7820
• Older LGR 915 analyzers
• The Picarro G2301
• The EGM-4
• The LI-COR LI-850
