Spaceborne Far‐Infrared Signal Simulations Over the Antarctic Plateau With Temperature‐Dependent Ice Cloud Optical Properties

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Longwave cloud radiative effects significantly influence variability in global and regional Earth systems. However, there have been very few, if any, measurements of the far‐infrared (FIR) radiation over the polar regions, where about half of the outgoing longwave radiation is in the FIR spectrum. This motivated the Polar Radiant Energy in the

Concurrent Cloud and Drizzle Observations From Synergistic Ground‐Based Measurements

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Drizzle, a common feature of marine boundary layer clouds formed through collision‐coalescence, plays a key role in cloud microphysics and evolution. However, simultaneously retrieving cloud and drizzle properties from remote‐sensing observations remains challenging because drizzle droplets often dominate radar signals, masking cloud ...

All-fiber multifunction differential absorption CO2 lidar integrating single-photon and coherent detection.

Optics Express
This study demonstrates a differential absorption lidar (DIAL) for CO2 that integrates both single-photon direct detection and coherent detection. Based on all-fiber 1572 nm wavelength devices, this compact lidar achieves detection of CO2 concentration ...

Toward Consistent Canopy Characterization From Low‐Cost UAV Imagery

Ecology and Evolution, Volume 16, Issue 9, September 2026.
We show that UAV‐based crown segmentation can reliably characterize dominant canopy trees in a structurally complex tropical forest. Focusing on these key individuals improves the assessment of forest structure and supports ecological monitoring at multiple scales. ABSTRACT Monitoring tropical forest structure at landscape scale requires cost‐effective

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 ...

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

Hydrological 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 ...
