Preliminary characterization of the Flux Gradient Method to estimate CO2 soil flux.

This thesis presents a preliminary characterization of the Flux Gradient Method (FGM) for estimating CO2 soil flux, evaluating its precision and reliability in measuring gas exchange at the surface-atmosphere interface. By analyzing concentration gradients and soil physical properties, the research identifies the key environmental variables and transport coefficients that influence flux calculations. The findings offer a comparative assessment of FGM against standard chamber-based techniques, highlighting its potential for continuous, non-intrusive monitoring of soil respiration across various ecosystems.
