Greenhouse gas (GHG) flux measurements are notoriously noisy. Sensors drift, weather disrupts sampling, and the relationship between soil conditions and gas emissions is non-linear. This post walks through the analytical approach used in environmental GHG research projects, using data from the EucFACE experiment as a reference.
The primary gases of interest in soil flux studies are:
Fluxes are typically measured in µmol m⁻² s⁻¹ (CO₂) or nmol m⁻² s⁻¹ (CH₄, N₂O).
