Uncertainty in eddy covariance measurements and its application to physiological models.
Flux data are noisy, and this uncertainty is largely due to random measurement error. Knowledge of uncertainty is essential for the statistical evaluation of modeled and measured fluxes, for comparison of parameters derived by fitting models to measured fluxes and in formal data-assimilation efforts. We used the difference between simultaneous measurements from two towers located less than 1 km...
متن کاملEddy Covariance Measurements over Grasslands
In this chapter we first provide a historic overview of – and outline some of the peculiarities associated with – grassland eddy covariance flux measurements, elaborate on the additional terms that need to be quantified when estimating the grassland net ecosystem carbon balance and finally discuss some of the challenges associated with upcoming nitrous oxide and methane flux measurements in man...
متن کاملUncertainty Due to Hygrometer Sensor in Eddy 1 Covariance Latent Heat Flux Measurements
9 Half-hour latent heat flux (LE) was measured over an early-maturing peach orchard 10 (Prunus persica L.) by two different hygrometers: 1) infrared gas analyzer (IRGA) (Li11 COR, model Li-7500); and 2) ultraviolet hygrometer (Campbell, KH20). A good 12 agreement between LE obtained with the IRGA (LEIRGA) and the KH20 (LEKH20) 13 hygrometers was observed. During rainy periods, LEIRGA and LEKH20...
متن کاملconstruction and validation of translation metacognitive strategy questionnaire and its application to translation quality
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
