InnFLUX – an open-source code for conventional and disjunct eddy covariance analysis of trace gas measurements: an urban test case [PDF]

Atmospheric Measurement Techniques, 2020
We describe and test a new versatile software tool for processing eddy covariance and disjunct eddy covariance flux data. We present an evaluation based on urban non-methane volatile organic compound (NMVOC) measurements using a proton transfer reaction ...

Estimation of Sensible and Latent Heat Fluxes Using Flux Variance Method under Unstable Conditions: A Case Study of Tea Plants

Atmosphere, 2022
Evapotranspiration is essential for precise irrigation and water resource management. Previous literature suggested that eddy covariance (EC) systems could directly measure evapotranspiration in agricultural fields.

Eddy Covariance: A Scientometric Review (1981-2018)

CoRR, 2022
The history of eddy covariance (EC) measuring system could be dated back to 100 years ago, but it was not until the recent decades that EC gains popularity and being widely used in global change ecological studies, with explosion of related work published in papers from various journals.

Technical note: Novel triple O₂ sensor aquatic eddy covariance instrument with improved time shift correction reveals central role of microphytobenthos for carbon cycling in coral reef sands [PDF]

Biogeosciences, 2021
The aquatic eddy covariance technique stands out as a powerful method for benthic O2 flux measurements in shelf environments because it integrates effects of naturally varying drivers of the flux such as current flow and light.

Predicting evapotranspiration from drone-based thermography – a method comparison in a tropical oil palm plantation [PDF]

Biogeosciences, 2021
For the assessment of evapotranspiration, near-surface airborne thermography offers new opportunities for studies with high numbers of spatial replicates and in a fine spatial resolution.

Globally Scalable Approach to Estimate Net Ecosystem Exchange Based on Remote Sensing, Meteorological Data, and Direct Measurements of Eddy Covariance Sites

Remote Sensing, 2022
Despite a rapid development of Nature-Based Solutions (NBS) for carbon removal in recent years, the methods for evaluating NBS still have certain gaps. We propose an approach based on a combination of remote sensing data and meteorological variables to ...

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

Earth 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]

Atmospheric 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 ...
