More than 60 years ago, the basics of the eddy-covariance method were proposed by Montgomery, Swinbank and Obukhov, with the first widely applicable sonic anemometers becoming available more than a decade later. For a long time, the method was only used by specialists like Dyer, Businger, ...
The eddy covariance technique ascertains the exchange rate of CO2 across the interface between the atmosphere and a plant canopy by measuring the covariance between fluctuations in vertical wind velocity and CO2 mixing ratio. Two decades ago, the method was employed to study CO2 exchange of agricult...
The eddy-covariance method is the primary way of measuring turbulent fluxes directly. Many investigators have found that these flux measurements often do not satisfy a fundamental criterion—closure of the surface energy balance. This study investigates to what extent the eddy-covariance measurement tech...
(ATMOS) project, a WCE that was shed from the Brazil Current was sampled. Apart from traditional meteorological measurements, we used the Eddy Covariance method to directly measure the ocean–atmosphere sensible heat, latent heat, momentum, and carbon dioxide (CO2) fluxes. The mechanisms of ...
We measured annual methane emission from a boreal minerotrophic fen, Siikaneva, by the eddy covariance method. The average wintertime emissions were below 1 mg m(-2) h(-1), and the summertime emissions about 3.5 mg m(-2) h(-1). The water table depth did have any clear effect on ...

Estimation of sensible and turbulent latent heat fluxes were done using the eddy covariance method44,45,46. Penetrating short wave radiation qpen was estimated based on Lotliker et al.47. The diffuse attenuation coefficient of photosynthetically available radiation (PAR) at wavelengths between 400–700...
The variance-covariance method makes use of covariances (volatilities and correlations) of the risk factors and the sensitivities of the portfolio values with respect to these risk factors with the goal of approximating the value at risk. This method leads directly to the final result, i.e., ...
