Improved time constant of a newly released air temperature sensor and its implications
Quarterly Journal of the Royal Meteorological Society, EarlyView.We set out laboratory response‐time evaluations for a recently released platinum resistance meteorological air temperature sensor from Campbell Scientific. The new sensor fully meets World Meteorological Organization and National Oceanic and Atmospheric Administration specifications for sub‐20 s 63% response time, even at airflow rates as low as 0.2 m ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.Using micrometeorological measurements in Brazil at the Amazon Tall Tower Observatory, the scalewise impact of thermal stratification on turbulent momentum fluxes is explored in the roughness sublayer and the atmospheric surface layer. A scalewise co‐spectral budget model developed here revealed that the turbulent momentum co‐spectrum Fwu(kx)$$ {F}_{wu}

Dynamic Continuous Variable Quantum Key Distribution for Securing a Future Global Quantum Network
Advanced Quantum Technologies, EarlyView.The article explores securing a dynamic global quantum network using continuous variable QKD, proposing a unified three‐layer network architecture for integrating existing QKD networks. It evaluates secret key rates across various channels and introduces the link capacity as a metric for determining the optimum path for secret key distribution in a ...

River Research and Applications, EarlyView.ABSTRACT By altering hydrological and geomorphological processes at watershed scales, humans have substantially influenced the movement of sediment on Earth's surface. Despite widespread recognition of human impacts on erosion and deposition, few studies have assessed the magnitude of change in watershed‐scale sediment fluxes before and after the ...

Hyperspectral imaging has a limited ability to remotely sense the onset of beech bark disease
Remote Sensing in Ecology and Conservation, EarlyView.Although hyperspectral imaging is a powerful remote sensing tool, it proved ineffective in predicting the progression of beech bark disease, except in its later stages, both at the canopy and leaf levels. While some alterations in chlorophyll, water content, and canopy structure may have influenced foliar reflectance at the canopy scale, as suggested ...
