Comparison of Daytime and Nighttime Ecosystem Respiration Measured by the Closed Chamber Technique on a Temperate Mire in Poland

Popis výsledku v původním jazyce

Ecosystem respiration (Reco) plays an important role in estimating the global carbon balance of terrestrial ecosystems, and knowledge of respiration is required to correctly assess the gross primary (GPP) production of such ecosystems. In our paper, daytime Reco fluxes are compared with nighttime CO2 fluxes which were measured manually by the closed chamber technique on a wetland site in Poland. The CO2 fluxes measurements were performed between July 2008 and May 2009. Our study indicated that there aresignificant differences between modeled daytime and nighttime Reco fluxes and that these differences are higher when the nighttime fluxes are restricted only to nights with stable atmospheric conditions. The nighttime sums of cumulative Reco are much higher than the one estimated for daytime conditions, while there is nearly no difference between daytime and nighttime sums of cumulative Reco, when the nighttime fluxes are restricted only for nights with turbulent atmospheric conditions.
