Maximizing the information obtained from chamber-based greenhouse gas exchange measurements in remote areas.

ABSTRACT: Measurements of greenhouse gas (GHG) fluxes, particularly methane (CH₄) and nitrous oxide (N₂O) in mountain ecosystems are scarce due to the complexity and unpredictable behavior of these gases, in addition to the remoteness of these ecosystems. In this context, we measured CO₂, CH₄, and N₂O fluxes in four semi-natural pastures in the Pyrenees to investigate their magnitude and range of variability. Our interest was to study GHG phenomena at the patch-level, therefore we chose to measure the gas-exchange using a combination of a gas analyzer and manual chambers. The analyzer used is a photoacoustic field gas-monitor that allows multi-gas instantaneous measurements. After implementing quality control and corrections, data was of variabl
