A Comparison Assessment of Measuring Evapotranspiration in Egypt [PDF]
Journal of Soil Sciences and Agricultural Engineering, 2021 Scarce water resources management makes accurate measurements of different parameters of water requirements very critical. Therefore, the values for crop evapotranspiration and crop water requirement are identical.

Methane emissions from an oil sands tailings pond: a quantitative comparison of fluxes derived by different methods [PDF]
Atmospheric Measurement Techniques, 2021 Tailings ponds in the Alberta oil sands region are significant sources of fugitive emissions of methane to the atmosphere, but detailed knowledge on spatial and temporal variabilities is lacking due to limitations of the methods deployed under current ...

Low-cost eddy covariance: a case study of evapotranspiration over agroforestry in Germany [PDF]
Atmospheric Measurement Techniques, 2019 Heterogeneous land surfaces require multiple measurement units for spatially adequate sampling and representative fluxes. The complexity and cost of traditional eddy covariance (EC) set-ups typically limits the feasible number of sampling units ...

Flux calculation of short turbulent events – comparison of three methods [PDF]
Atmospheric Measurement Techniques, 2017 The eddy covariance method is commonly used to calculate vertical turbulent exchange fluxes between ecosystems and the atmosphere. Besides other assumptions, it requires steady-state flow conditions.

First eddy covariance flux measurements by PTR-TOF [PDF]
Atmospheric Measurement Techniques, 2010 The recently developed PTR-TOF instrument was evaluated to measure methanol fluxes emitted from grass land using the eddy covariance method. The high time resolution of the PTR-TOF allowed storing full mass spectra up to <i>m/z</i> 315 with a

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 ...

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.
