The chamber method is one of the most widely used techniques to measure the concentration and fluxes of greenhouse gases such as CO₂, CH₄, and N₂O between the soil or water surface and the atmosphere. This method is especially useful in ecological, agricultural, and climate change research.
The automated chamber method is an advanced version of the traditional manual chamber technique, designed to improve accuracy, reduce measurement errors, and enhance the efficiency of greenhouse gas monitoring.
Compared to manual chambers, the automated chamber system enables continuous monitoring, reduces labor intensity, and minimizes human-induced bias in the measurements.
A chamber is a sealed enclosure placed on the monitoring surface (soil, water, vegetation). Over a defined period, the air inside the chamber is sampled or directly analyzed to determine changes in greenhouse gas concentrations. Based on these changes, the system calculates emission or uptake rates.
The system operates 24/7 continuously and can be integrated with other environmental sensors such as temperature, humidity, and atmospheric pressure to improve measurement accuracy.
Scientific Research: Precisely measures CO₂, CH₄, and N₂O fluxes to support emission model calibration and analysis of carbon/nitrogen cycles.
Ecological Studies: Evaluates the role of ecosystems (e.g., forests, wetlands) in GHG sequestration or emission.
Sustainable Agriculture: Assesses emissions from various agricultural practices and mitigation strategies (e.g., AWD irrigation, fertilizers, crop rotation, biochar, soil management, no-till farming) for emission accounting and carbon labeling of agricultural products.
Carbon Credit Projects: Provides MRV (Measurement, Reporting, Verification) data for agriculture, forestry, and waste management methodologies under international standards such as Verra and Gold Standard.
