Predicting Electrically Generated Hydrogen Oxides From Ultraviolet Radiation Emissions
Abstract Electrical discharges such as lightning and corona discharges generate extreme amounts of hydroxyl radical (OH), the atmosphere's most important oxidizer, enough for electrical discharges to be a globally significant source of OH. However, there are few field measurements of electrically generated OH (LOH), hindering attempts to better ...

Abstract As large wildfires become more frequent and severe in North America due to heightened fuel aridity and fire weather conditions driven by anthropogenic climate change, wildfire smoke has an increasingly important influence on air quality. Transported smoke can impact urban boundary layer ozone (O3) directly, via the entrainment of O3 formed in ...

This report presents an 8‐inch quasi‐standard piezoelectric integrated MEMS technology (PIMT) platform which, through the integration of core and additional processes, reliably supports three rounds of multi‐project wafer (MPW) fabrication. Whilst ensuring support for mass production processes, the platform offers certain flexibility, providing a ...

TRIM: Simultaneous Thermometry, Ranging, and Imaging via a Monolithic Metalens
ABSTRACT While metasurfaces offer a pathway beyond the discrete architectures of conventional LWIR systems, physically fusing high‐precision thermometry and passive ranging onto a single metalens remains a formidable challenge. Here, we demonstrate a monolithic, dual‐focus metalens capable of simultaneous multidimensional sensing.

We show that temperature and solar radiation shape insect community traits in scale‐dependent ways across German forests. Whereas macroclimatic temperature predicts consistent shifts in body size and colouration, microclimatic variation driven by canopy structure can override these broad patterns, producing contrasting trait filtering among taxa ...

Research on the Correction Algorithm for Ozone Inversion in Differential Absorption Lidar
Due to the complex and variable nature of the atmospheric conditions, traditional multi-wavelength differential absorption lidar (DIAL) methods often suffer from significant errors when inverting ozone concentrations.

Abstract Resource subsidies, or the flow of energy across ecosystem boundaries, can influence community structure and function and act as important nutrient sources to less productive ecosystems, particularly in marine and coastal zones. Coastal dunes, connected to the nearshore through sandy beaches, likely depend on the delivery of marine subsidies ...

A primer on forest structure measurement with lidar for ecologists
Abstract Light detection and ranging (lidar) technology has fundamentally advanced the way we measure forest structure, facilitating new insights into ecological processes. Lidar for forest ecology applications is deployed on multiple types of platforms that operate from the ground, air, or space, and each has associated strengths and limitations ...

Impact of an extreme storm event on a multiple intertidal barred coastal system
Extreme storms do not necessarily cause extreme coastal erosion. Integrated DGPS surveys and SWAN nearshore wave modelling reveal that Storm Barra's peak coincided with a low‐tide stage, allowing multiple intertidal bars (MITBs) to dissipate incoming wave energy before it reached Dundrum Bay's shoreline, highlighting the combined role of tidal stage ...

An Improved CH4 Profile Retrieving Method for Ground-Based Differential Absorption Lidar
Range-resolved CH4 concentration measurement is important prior data for atmospheric physical and chemical models. Ground-based differential absorption lidar (DIAL) can measure the vertical distribution of CH4 concentration in the atmosphere.
