- •
Continuous monitoring of soil CO2 efflux is accommodated by a Forced Diffusion (FD) chamber system in all locations and weather conditions.
- •
Temperature and thaw depth are important parameters for influencing soil CO2 emissions.
- •
Growing and non-growing season simulated soil carbon represent 75.7 and 24.3% of annual carbon emissions, respectively.
- •
Annual CO2emission with FD chamber would be an effective for quantifying growing and non-growing seasons soil carbon budget in the Arctic.
