WebAbstract. Measuring in situ soil fluxes of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) continuously at high frequency requires appropriate technology. We tested the combination of a commercial automated soil CO2 flux chamber system (LI-8100A) with a CH4 and N2O analyzer (Picarro G2308) in a tropical rainforest for 4 months. A chamber … WebAnother is to continuously monitoring the soil gas using the standard RAD7 protocol, in which the instrument’s pump operates intermittently, pulling soil gas into the measurement chamber at a low rate of speed. The third mode involves continuous pump activity and short 5-minute cycles, making it possible to measure thoron in soil gas.
