Targeted observations with an airborne wind lidar [PDF]

, 2005
This study investigates the possibilities and limitations of airborne Doppler lidar for adaptive observations over the Atlantic Ocean. For the first time, a scanning 2-µm Doppler lidar was applied for targeted measurements during the Atlantic The ...

Responsive Phase Gradient Metasurface for Laser Stealth and Dynamic Thermal Camouflage

Laser &Photonics Reviews, Volume 20, Issue 17, 3 September 2026.
The graphical abstract depicts a phase‐gradient metasurface enabling directional scattering and emissivity‐controlled thermal radiation. The engineered phase profile redistributes the reflected optical momentum, suppressing specular reflection and generating non‐specular scattering.

Remote Sensing With Machine Learning to Monitor Seagrass Meadows: Long‐Term Trends in Tauranga Harbour, New Zealand

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.
Seagrass meadows play critical roles in coastal ecosystems by stabilising sediments, supporting biodiversity and sequestering carbon, yet monitoring their recovery at scale is often constrained by the lack of scalable and repeatable approaches. This study applies an open‐source remote‐sensing framework to track long‐term changes in Zostera muelleri in ...

Research on the Correction Algorithm for Ozone Inversion in Differential Absorption Lidar

Photonics
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.

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

Journal of Field Robotics, Volume 43, Issue 6, Page 4037-4060, September 2026.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.

Ferric Chloride: The Venusian Unknown UV Absorber?

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Near‐ultraviolet imaging of the planet Venus reveals inhomogeneous absorption features in the otherwise bright clouds. This absorption has been studied for nearly 100 years, but identification of the near‐UV absorber remains one of the largest open questions in Venusian research.

Inside the Fire Plume Chemical Interactions: A Review on Key Processes and Future Directions

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Fire plumes are rising columns of heated air masses, consisting of gaseous and particulate matter generated by combustion, affecting air quality, climate and public health. The chemical species released undergo secondary reactions and participate in chemical and physical interactions, altering the properties of the fire plume.

Airborne lidar observations supporting the ADM-Aeolus mission for global wind profiling [PDF]

, 2012
The Atmospheric Dynamics Mission ADM-Aeolus of ESA will be the first lidar mission to sense the global wind field from space. The instrument is based on a direct-detection Doppler lidar operating at 354.9 nm with two spectrometers for aerosol/cloud ...
