Meteorology and geography, more than biological traits, drive variation in frog phenology across decades. [PDF]

Ecology
Abstract The fate of a species is a function of interacting environmental and biological processes. Disentangling the roles and interactions of such processes can elucidate the breadth of possible responses to global change, for instance, the potential for phenotypic plasticity or trait evolution to rescue populations from climate change.

Bridging the Energy Balance Gap in Eddy-Covariance Measurements: Insights From Standardized Network Data. [PDF]

Glob Chang Biol
Written Summary: Measuring energy exchanges between land and atmosphere is fundamental to understanding climate, but these measurements are systematically incomplete, with 20%–40% of energy consistently unaccounted for. Analyzing data from 84 sites worldwide, we show that carefully tracking all energy components and applying strict data quality filters

Net ecosystem CO₂ exchange measurements by the closed chamber method and the eddy covariance technique and their dependence on atmospheric conditions [PDF]

Atmospheric Measurement Techniques, 2014
Carbon dioxide flux measurements in ecosystem sciences are mostly conducted by eddy covariance technique or the closed chamber method. But there is a lack of detailed comparisons that assess present differences and uncertainties.

Prerequisites for application of hyperbolic relaxed eddy accumulation on managed grasslands and alternative net ecosystem exchange flux partitioning [PDF]

Atmospheric Measurement Techniques, 2014
Relaxed eddy accumulation is still applied in ecosystem sciences for measuring trace gas fluxes. On managed grasslands, the length of time between management events and the application of relaxed eddy accumulation has an essential influence on the ...

Choosing an optimal β factor for relaxed eddy accumulation applications across vegetated and non-vegetated surfaces [PDF]

Biogeosciences, 2021
Accurately measuring the turbulent transport of reactive and conservative greenhouse gases, heat, and organic compounds between the surface and the atmosphere is critical for understanding trace gas exchange and its response to changes in climate and ...

Quantitative analysis of the radiation error for aerial coiled-fiber-optic distributed temperature sensing deployments using reinforcing fabric as support structure [PDF]

Atmospheric Measurement Techniques, 2017
In recent years, the spatial resolution of fiber-optic distributed temperature sensing (DTS) has been enhanced in various studies by helically coiling the fiber around a support structure.

A horizontal mobile measuring system for atmospheric quantities [PDF]

Atmospheric Measurement Techniques, 2014
A fully automatic horizontal mobile measuring system (HMMS) for atmospheric quantities has been developed. The HMMS is based on the drive mechanism of a garden railway system and can be installed at any location and along any measuring track.

Influence of Different Methods to Estimate the Soil Thermal Properties from Experimental Dataset

Land, 2022
Knowledge of soil thermal properties (diffusivity (k) and conductivity (λ)) is important to understand the soil–plant–atmosphere interaction related to the physical and biological processes associated with energy transfer and greenhouse gas exchanges ...

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.
