Record‐Breaking Easterly Dust Transport From North Africa to the Arctic: An Observational Study

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Mineral dust drives Arctic climate variability, but accurate source attribution remains difficult due to plume mixing from the different regions. Using observations and HYSPLIT modeling, we characterize a record‐breaking trans‐continental dust intrusion (March 13–19, 2013) traversing from North Africa to the Arctic. Distinct from single‐source

Comparison of Airborne Water Vapor Lidar Observations with ECMWF Analyses and first Assimilation Experiments

, 2006
Water vapor is the most important greenhouse gas and controls cloud formation and the evolution of weather systems. As its tropospheric concentration may rapidly vary over four orders of magnitude, accurate monitoring of water vapor, especially in the ...

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

InfoMat, Volume 8, Issue 7, July 2026.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Triple-Pulsed Two-Micron Integrated Path Differential Absorption Lidar: A New Active Remote Sensing Capability with Path to Space

EPJ Web of Conferences, 2016
The two-micron wavelength is suitable for monitoring atmospheric water vapor and carbon dioxide, the two most dominant greenhouse gases. Recent advances in 2-μm laser technology paved the way for constructing state-of-the-art lidar transmitters for ...

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers

River Research and Applications, Volume 42, Issue 6, Page 1115-1141, July 2026.
ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

Towards more accurate water vapour observations: Airborne lidar measurement examples and characteristics

, 2006
Airborne differential absorption lidar measurements of mid-latitude, subtropical and tropical water vapour were performed during several recent campaigns over North and South America, and Australia, as well as on the corresponding long-range transfer ...

First attempt to monitor atmospheric glyoxal using differential absorption lidar

, 2012
Glyoxal (CHOCHO), as an indicator of photochemical “hot spots”, was for the first time the subject of a differential absorption lidar (DIAL) campaign. The strongest absorption line of glyoxal in the blue wavelength region – 455.1 nm – was chosen as the ...
