Eddy Covariance Measurements over Crops
2011Croplands are managed ecosystems with rapid development over the course of the growing season under nearly optimal growth conditions with respect to nutrient availability (fertilization), water availability (possible irrigation in dry conditions), competition (monocultures where herbicide and fungicides applications keep other competitors off the plot)

This chapter examines the relationship between eddy covariance calculations and the concept of net ecosystem exchange. Eddy covariance is a class of micrometeorological method that measures the fluxes of energy, water, and trace gases between the earth’s surface and the atmosphere.

Eddy Covariance Measurements over Wetlands
2011Wetland ecosystems can be classified according to various systems, one of which defines three major groups: (1) northern peatlands (with a total area of 350×106 ha), (2) freshwater swamps and marshes (204×106 ha), and (3) coastal wetlands (36×106 ha) (Mitsch et~al. 2009).

Exploring Eddy-Covariance Measurements Using a Spatial Approach: The Eddy Matrix
Boundary-Layer Meteorology, 2016Taylor’s frozen turbulence hypothesis states that “standard” eddy-covariance measurements of fluxes at a fixed location can replace a spatial ensemble of instantaneous values at multiple locations. For testing this hypothesis, a unique turbulence measurement set-up was used for two measurement campaigns over desert (Namibia) and grassland (Germany) in ...

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.

Eddy Covariance and Artificial Intelligence: a review
The Eddy Covariance (EC) method allows for the monitoring of carbon, water, and energy fluxes between Earth’s surface and atmosphere. Due to it’s varying interdependent data streams and abundance of data as a whole, EC is naturally suited to Artificial Intelligence (AI) approaches.Arianna Lucarini +4 more

Ship Borne Direct Eddy Covariance Flux Measurements
2015Ship borne direct eddy covariance flux measurements of momentum, heat (latent and sensible), and the trace gas CO2, were conducted during three open ocean experiments. The methods for data analysis and interpretation were adapted from the literature, and reviewed carefully.

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

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 ...
