Uncertainty of evapotranspiration fluxes measured with eddy covariance
2020<p>The project MOMENT (Model Monitoring EveNTs) investigates the interplay between carbon and water cycles with special focus on the impacts of drought and heatwaves as well as their long-term trends. This project aims to investigate new monitoring and modeling methods to explain the interplay between carbon and water cycles of ...

Eddy Covariance Measurements Over Urban Areas
2011Throughout the last two decades, numerous research projects applied the eddy covariance (EC) approach to urban ecosystems to directly measure turbulent fluxes between the urban surface and the atmosphere to quantify the exchange of energy, water vapor, greenhouse gases, air pollutants, and aerosols in connection with the assessment of (air pollutant ...

Water Flux Partitioning for Eddy Covariance Data
2020<p>Here we present an overview of methods for partitioning evapotranspiration (ET) from eddy covariance data. We focus on methods that are designed to use the core energy and carbon fluxes, as well as meteorological data, and do not require supplemental measurements or campaigns.

Compact EDDY: a compact, low consumption eddy covariance logging system
2008Compact_Eddy is a handheld computer-based logging system developed for eddy covariance installations. It is flexible to support different types of sonic anemometers, it has storing capability on internal memory, and data processing capability. The software is written in the Visual Basic .NET platform, entirely based on standard Windows operating ...

Methodological challenges for understory eddy-covariance measurements
Understory eddy-covariance measurements provide valuable insights into ecosystem CO2 exchange processes, particularly in understanding the interplay between understory and overstory exchange processes. However, their placement deep within the canopy presents some methodological challenges not typically encountered in standard eddy-covariance ...Alexander Platter +2 more

Pitfalls and precautions for understory eddy-covariance processing
Understory, so within-canopy, eddy-covariance (EC) measurements of energy, water, or CO2 fluxes offer more detailed insights into ecosystem exchange dynamics. Deriving these fluxes from EC systems requires several processing steps, where some of them are only valid for the inertial sublayer (i.e., above the canopy).Alexander Platter +2 more

Metrology for fluxes: eddy covariance measurement uncertainty
The uncertainty evaluation of eddy covariance flux measurements has been thoroughly developed in the last two decades. However, the various methods proposed are not yet fully compliant with the internationally accepted metrological guidelines, e.g. those indicated in the Guide to expression of uncertainty in measurement and related supplements issued ...Nicola Arriga, Alberto Bottacin
