Effect of measurement time of the day on the relationship between temperature and soil CO2 Efflux
Original language description
In this study we investigated effect of the time of the day when manual measurements of soil CO2 efflux are performed on estimates of seasonal sums of released carbon from the soil. We subsampled continuous measurement of soil CO2 efflux into six sets ofdata? 0 h, 4 h, 8 h, 12 h, 16 h and 20 h. To estimate seasonal carbon flux from the soil we used continuously measured soil temperature and parameters R10 and Q10 calculated from continuous measurements and from measurements taken at individual hours. Q10 calculated from 12 h and 16 h data were lower than Q10 calculated from continuous measurements. On the contrary, Q10 at 0 h, 4 h, 8 h and 20 h were higher.Seasonal carbon flux from the soil based on 0 h, 4 h and 8 h measurements was overestimated compare to the flux calculated from continuous measurements. On the contrary, measurements at 12 h, 16 h and 20 h measurements underestimated the carbon flux. The under- or overestimation was significant for 0 h, 4 h, 8 h and 20 h data sets.
