Chamber techniques versus eddy covariance method during nighttime measurements
Original language description
The parameter Q10 is commonly used to express the relationship between soil CO2 efflux and soil temperature. Soil surface CO2 efflux and soil temperature at different depths were measured in a 21-year-old Norway spruce stand and a mountain grassland site(Bily Kriz, Beskydy Mts., Czech Republic), using automated gasometric systems. A time-delay and goodness-of-fit between soil CO2 efflux and soil temperature at different measuring depths were determined. Wide ranges of values for the time-delay of CO2 efflux in response to temperature, Q10 and the determination coefficient (R2) between CO2 efflux and temperature were obtained. The values of Q10 and the CO2 time-delay increased with depth of soil temperature measurement point, while the R2 of the CO2-temperature relationship significantly decreased. Measurement of soil temperature at very shallow soil layer, preferably at the soil surface, is highly recommended to determine useable values of Q10.
