Eddy covariance measurement of isoprene fluxes [PDF]
A system has been developed to directly measure isoprene flux above a forest canopy by eddy covariance using the combination of a fast response, real‐time isoprene sensor and sonic anemometer. This system is suitable for making nearly unattended, long‐term, and continuous measurements of isoprene fluxes. Isoprene detection is based on chemiluminescence

Comparative measurements of water vapor fluxes over a tall forest using open- and closed-path eddy covariance system [PDF]
Eddy covariance using infrared gas analyzes has been a useful tool for gas exchange measurements between soil, vegetation and the atmosphere. So far, comparisons between the open- and closed-path eddy covariance (CP) system have been extensively made on ...

Bubble-Mediated Gas Transfer and Gas Transfer Suppression of DMS and CO2 [PDF]
Direct dimethyl sulfide (DMS) flux measurements using eddy covariance have shown a suppression of gas transfer at medium to high wind speed. However, not all eddy covariance measurements show evidence of this suppression.

Comparison of evapotranspiration estimates using the water balance and the eddy covariance methods
The eddy covariance method estimates the energy flux of latent heat for evapotranspiration. However, imbalance between the land surface energy output and input is a well‐known fact.

Evaluation of a lower-powered analyzer and sampling system for eddy-covariance measurements of nitrous oxide fluxes [PDF]
Nitrous oxide (N2O) fluxes measured using the eddy-covariance method capture the spatial and temporal heterogeneity of N2O emissions. Most closed-path trace-gas analyzers for eddy-covariance measurements have large-volume, multi-pass absorption cells ...

Benthic oxygen exchange in a live coralline algal bed and an adjacent sandy habitat: an eddy covariance study [PDF]
Coralline algal (maerl) beds are widespread, slow-growing, structurally complex perennial habitats that support high biodiversity, yet are significantly understudied compared to seagrass beds or kelp forests.

In this paper we present one year of meteorological and flux measurements obtained near Ny-Ålesund, Spitsbergen. Fluxes are derived by the eddy covariance method and by a hydrodynamic model approach (HMA) as well.

The southern South China coastal oceans within the South East Asian region are much lacking in the perception of the surface energy budget and evaporation over the ocean waters in response to climatic changes.

Quantifying the impact of emission outbursts and non-stationary flow on eddy-covariance CH4 flux measurements using wavelet techniques [PDF]
Methane flux measurements by the eddy-covariance technique are subject to large uncertainties, particularly linked to the partly highly intermittent nature of methane emissions. Outbursts of high methane emissions, termed event fluxes, hold the potential

Does increased spatial replication above heterogeneous agroforestry improve the representativeness of eddy covariance measurements? [PDF]
Spatial heterogeneity in terrestrial ecosystems compromises the accuracy of eddy covariance measurements. Examples of heterogeneous ecosystems are temperate agroforestry systems, which have been poorly studied by eddy covariance.
