The Role of Lightning in Atmospheric Chemistry

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Lightning has important effects on atmospheric constituents in primarily the middle and upper troposphere. We summarize the effects of lightning on atmospheric chemistry that have been published since the last major review in 2007. The estimates of NOx production by lightning (LNOx) are based on five methods: theoretical/laboratory estimates ...

First Assessment of ICESat‐2 Summer Sea Ice Freeboard With Airborne Validation

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract ICESat‐2 has demonstrated solid performance in retrieving sea ice freeboard during winter, when sea ice surface types are well‐defined and leads provide reliable sea surface height references. Summer retrievals are challenging because melt ponds are not explicitly distinguished in the ATL07 surface classification and may be identified as ice ...

Predicting Electrically Generated Hydrogen Oxides From Ultraviolet Radiation Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
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 ...

LIDAR WAVEFORM SIMULATION OVER COMPLEX TARGETS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Unlike discrete-return LIDAR system that measures the return times of some echoes, waveform LIDAR provides the full-waveform data by digitising multi-echoes. From the waveform data we can extract more information about the geometry and reflectance of the

A primer on forest structure measurement with lidar for ecologists

Ecosphere, Volume 17, Issue 8, August 2026.
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 ...

A Concealed Car Extraction Method Based on Full-Waveform LiDAR Data [PDF]

Mobile Information Systems, 2016
Concealed cars extraction from point clouds data acquired by airborne laser scanning has gained its popularity in recent years. However, due to the occlusion effect, the number of laser points for concealed cars under trees is not enough. Thus, the concealed cars extraction is difficult and unreliable.
