Energy balance closure for the LITFASS-2003 experiment [PDF]

open access: yes, 2010
In the first part, this paper synthesises the main results from a series of previous studies on the closure of the local energy balance at low-vegetation sites during the LITFASS-2003 experiment.

MICROMETEOROLOGICAL AND SAP FLOW MEASUREMENT OF WATER VAPOUR EXCHANGES IN OLIVE: SCALING UP FROM CANOPY TO ORCHARD [PDF]

open access: yes, 2009
A comparison of water consumption evaluated at tree and orchard level was carried out in a commercial olive orchard located in Sicily using up-scaled sap-flow evapotranspiration estimations and eddy covariance measurements. Sap flow probes were installed

Soil respiration in a northeastern US temperate forest: a 22‐year synthesis [PDF]

open access: yes, 2013
To better understand how forest management, phenology, vegetation type, and actual and simulated climatic change affect seasonal and inter‐annual variations in soil respiration (Rs), we analyzed more than 100,000 individual measurements of soil ...

The INFLUX network – eddy covariance in and around an urban environment [PDF]

open access: yesEarth System Science Data
The eddy covariance method is used by various disciplines to measure atmospheric fluxes of both vector and scalar quantities. One long-term, multi-site urban flux network experiment was the Indianapolis Flux Experiment (INFLUX), which successfully ...

Chemical sensor resolution requirements for near-surface measurements of turbulent fluxes [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
Businger and Delany (1990) presented an approach to estimate the sensor resolution required to limit the contribution of the uncertainty in the chemical concentration measurement to uncertainty in the flux measurement to 10 % for eddy covariance ...

Using Stochastic Ray Tracing to Simulate a Dense Time Series of Gross Primary Productivity

open access: yesRemote Sensing, 2015
Eddy-covariance carbon dioxide flux measurement is an established method to estimate primary productivity at the forest stand level (typically 10 ha).

Eddy covariance raw data processing for CO2 and energy fluxes calculation at ICOS ecosystem stations [PDF]

open access: yes, 2019
open18siThe eddy covariance is a powerful technique to estimate the surface-Atmosphere exchange of different scalars at the ecosystem scale. The EC method is central to the ecosystem component of the Integrated Carbon Observation System, a monitoring ...

Improved Post-processing of Eddy-Covariance Data to Quantify Atmosphere–Aquatic Ecosystem CO2 Exchanges

open access: yesFrontiers in Marine Science, 2018
The capture of carbon by aquatic ecosystems and its sequestration in sediments has been studied as a potential method for mitigating the adverse effects of climate change.

Comparative CO2 flux measurements by eddy covariance technique using open- and closed-path gas analysers over the equatorial Pacific Ocean [PDF]

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2012
Direct comparison of air–sea CO2 fluxes by open-path eddy covariance (OPEC) and closed-path eddy covariance (CPEC) techniques was carried out over the equatorial Pacific Ocean.
