Eddy Covariance Measurements over Grasslands [PDF]
, 2012 Chapitre 13International audienceIn 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 ...

Ergodicity test of the eddy-covariance technique [PDF]
Atmospheric Chemistry and Physics, 2015 The ergodic hypothesis is a basic hypothesis typically invoked in atmospheric surface layer (ASL) experiments. The ergodic theorem of stationary random processes is introduced to analyse and verify the ergodicity of atmospheric turbulence measured using ...

Ecosystem Transpiration from Eddy Covariance [PDF]
, 2021 Transpiration is an integral part of the earth system, not only because plant water use is the dominant path by which water flows from the soil to the atmosphere, but also because water loss from leaves is intrinsically connected to CO2 uptake and ...

Towards a consistent eddy-covariance processing: an intercomparison of EddyPro and TK3 [PDF]
Atmospheric Measurement Techniques, 2014 A comparison of two popular eddy-covariance software packages is presented, namely, EddyPro and TK3. Two approximately 1-month long test data sets were processed, representing typical instrumental setups (i.e., CSAT3/LI-7500 above grassland and Solent R3/

Eddy Covariance Theory: A Review. [PDF]
Glob Chang BiolABSTRACT Eddy covariance (EC), the gold standard for measuring ecosystem scale gas and heat exchanges, has transformed our understanding of the breathing of the biosphere, and thus global change biology. Despite numerous methodological improvements and insights gained from the technique, the community faces persistent challenges that ...

A performance evaluation of despiking algorithms for eddy covariance data. [PDF]
Sci Rep, 2021 AbstractSpike detection for raw high-frequency eddy covariance time series is a challenging task because of the confounding effect caused by complex dynamics and the high level of noise affecting such data. To cope with these features, a new despiking procedure rooted on robust functionals is proposed.

The North Wyke Farm Platform: Eddy Covariance Greenhouse Gas Data [PDF]
, 2023 The North Wyke Farm Platform (NWFP) was established in 2010 to study and improve grassland livestock production at the farm-scale. The NWFP uses a combination of environmental sensors, routine field and lab-based measurements, and detailed management ...

Eddy Covariance: A Scientometric Review (1981-2018)
CoRR, 2022 The history of eddy covariance (EC) measuring system could be dated back to 100 years ago, but it was not until the recent decades that EC gains popularity and being widely used in global change ecological studies, with explosion of related work published in papers from various journals.
