Solid-Phase Reference Baths for Fiber-Optic Distributed Sensing [PDF]

open access: yesSensors, 2022
Observations from Raman backscatter-based Fiber-Optic Distributed Sensing (FODS) require reference sections of the fiber-optic cable sensor of known temperature to translate the primary measured intensities of Stokes and anti-Stokes photons to the ...

Bioeconomy and Climate Change: The Scenarios of Food Insecurity in Brazil’s Northern Region (Amazon) Due to the Shift from Traditional Table Crops to Globally Valued Commodities [PDF]

open access: yesFoods
Climate variability directly influences agriculture, especially in a scenario of global change and transition to a sustainable bioeconomy. This study analyzed historical series (1994–2023) of productivity and harvested area of annual crops (corn, cassava,

The Micrometeorology of the Haifa Bay Area and Mount Carmel during the Summer

open access: yesAtmosphere, 2021
The Haifa bay area (HBA), which includes Mount Carmel and the Zevulun valley is the third largest metropolitan area in Israel. It is also a centre of heavy industry and an important transportation hub which serve as sources of local anthropogenic ...

Forward-Looking Infrared Cameras for Micrometeorological Applications within Vineyards [PDF]

open access: yesSensors, 2016
We apply the principles of atmospheric surface layer dynamics within a vineyard canopy to demonstrate the use of forward-looking infrared cameras measuring surface brightness temperature (spectrum bandwidth of 7.5 to 14 μm) at a relatively high temporal ...

Calyx and Corolla as Heliocaminiform Structures Enhance the Reproductive Adaptation of Brandisia hancei (Orobanchaceae) to Low Winter Temperatures [PDF]

open access: yesEcology and Evolution
The thermoregulation of plants through the heliocaminiform effect of hollow structures is widespread but overlooked. Winter‐flowering plants in subtropical regions often suffer from low temperatures; however, the reproductive adaptations of these plants ...

Toward quantifying turbulent vertical airflow and sensible heat flux in tall forest canopies using fiber-optic distributed temperature sensing [PDF]

open access: yesAtmospheric Measurement Techniques, 2023
The paper presents a set of fiber-optic distributed temperature sensing (FODS) experiments to expand the existing microstructure approach for horizontal turbulent wind direction by adding measurements of turbulent vertical component, as well as turbulent

The Large eddy Observatory, Voitsumra Experiment 2019 (LOVE19) with high-resolution, spatially distributed observations of air temperature, wind speed, and wind direction from fiber-optic distributed sensing, towers, and ground-based remote sensing [PDF]

open access: yesEarth System Science Data, 2022
The weak-wind stable boundary layer (wwSBL) is poorly described by theory and breaks basic assumptions necessary for observations of turbulence. Understanding the wwSBL requires distributed observations capable of separating between sub-mesoscales and ...

The NY-Ålesund TurbulencE Fiber Optic eXperiment (NYTEFOX): investigating the Arctic boundary layer, Svalbard [PDF]

open access: yesEarth System Science Data, 2021
The NY-Ålesund TurbulencE Fiber Optic eXperiment (NYTEFOX) was a field experiment at the Ny-Ålesund Arctic site (78.9∘ N, 11.9∘ E) and yielded a unique meteorological data set.

Distributed observations of wind direction using microstructures attached to actively heated fiber-optic cables [PDF]

open access: yesAtmospheric Measurement Techniques, 2020
The weak-wind boundary layer is characterized by turbulent and submesoscale motions that break the assumptions necessary for using traditional eddy covariance observations such as horizontal homogeneity and stationarity, motivating the need for an ...
