| Description
| - This paper discusses the advantages and disadvantages of the different methods that separate (NEE) into its major components, gross ecosystem carbon uptake (GEP) and ecosystem respiration (Reco.in Particular, we analyse the effect of the extrapolation of night-time values of ecosystem respiration into the daytime,this is usually done with a temperature response function that is derived from long-term data sets.We show that the temperature sensitivity of Reco, derived from long-term (annual) data sets, does not reflect the short-term temperature sensitivity that is effective when extrapolating from night-to daytime.Specifically,in summer active ecosystems the long-term temperature sensitivity exceeds the short-term sensitivity. Thus,in those ecosystems,the application of a long-term temperature sensitivity to the extrapolation of respiration from night to day leads to a systematic overestimation of ecosystem respiration from half-hourly to annual time-scales, which can reach 25%

- Toto pojednání se zabývá výhodami a nevýhodami, které separují NEE do jeho hlavních komponent – hrubý příjem uhlíku (GEP) a respirace ekosystému (Reco). Analyzovala se extrapolace nočních hodnot ekosystémové respirace do denních hodnot. Bylo zjištěno, že teplotní citlivost na respiraci derivovaná z ročních chodů nereflektuje krátkodobou citlivost teploty. Zvláště v létě překračuje dlouhodobá teplotní citlivost krátkodobou. V některých ekosystémech využití dlouhodobé teplotní citlivosti z noci na den systematicky nadhodnocuje ekosystémovou respiraci, která může dosáhnout více jak 25% pro celkovou roční sumu a která tak ovlivňuje GEP. Představili jsme nový algoritmus, který derivuje krátkodobou teplotní citlivost respirace z eddy kovariance, extrapoluje z nočních na denní data a využívá data z eddy kovariance a toků a z ukazatelů meteorologických dat a časové struktury toků.
