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

open access: yes, 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 ...

Woody Vegetation Dynamics Beyond the Treeline: Identifying Limiting Processes and Their Tipping Points

open access: yesGlobal Change Biology Communications, Volume 1, Issue 3, September 2026.
Illustration of temporal trends in Arctic and alpine woody vegetation under changing growth conditions (summer temperature and winter snowpack). Upper panel: example of shrub expansion in southern France (photograph included). Greening is detected via increasing NDVI (Normalized Difference Vegetation Index).

Thermal Regime Dynamics in a Karst Watershed Influenced by Groundwater and Urbanization

open access: yesHydrological Processes, Volume 40, Issue 9, September 2026.
This study investigates how groundwater and urban development shape stream temperature patterns in the karstic Spring Creek watershed of central Pennsylvania, USA. Using high‐resolution monitoring, we found that groundwater inputs buffer temperature in some streams, while urbanised sub‐catchments experience extreme thermal surges due to heated runoff ...

Responsive Phase Gradient Metasurface for Laser Stealth and Dynamic Thermal Camouflage

open access: yesLaser &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.
