High‐Resolution LiDAR Observations for Coupled Effects of Dry‐Air Entrainment and Haze‐Cloud Interactions on Cloud Vertical Structure

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract This study demonstrates the high‐resolution profiling of cloud microphysics in a laboratory chamber using Time‐Correlated Single Photon Counting (TCSPC) LiDAR. We present a novel retrieval method to derive vertical extinction (σ) $(\sigma )$ profiles, constrained by in situ measurements, to diagnose responses to dry‐air entrainment.

Increasing the Spatial and Temporal Resolution of Snow Water Equivalent Estimates Using SNOTEL Data and Low‐Cost Sensing

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 4, August 2026.
ABSTRACT Accurate estimation of snow water equivalent (SWE) is critical for understanding hydrologic processes in snow‐dominated watersheds. This study presents a method for improving the spatial and temporal resolution of SWE estimates using low‐cost snow depth sensors, manual snow sampling, and snow density data from nearby SNOwpack TELemetry (SNOTEL)

Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

Sedimentology, Volume 73, Issue 5, Page 1378-1402, August 2026.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

Structure‐Aware Unsupervised Transmission Corridor Structure Extraction From 3DEP Lidar Using Graph Attention Embeddings and Reinforcement‐Learned DBSCAN

Transactions in GIS, Volume 30, Issue 5, August 2026.
ABSTRACT Transmission corridors are critical components of power delivery infrastructure, and their large‐area monitoring increasingly relies on national‐scale airborne lidar programs. This study presents an unsupervised, scalable framework for extracting transmission corridor structures (including conductors and supporting towers) from U.S. Geological

Analyses of Atmospheric Turbulence Near Surface Observed by Uncrewed Aerial Vehicle in the Suburban Area of Seoul Metropolitan, South Korea

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract As the use of uncrewed aerial vehicles (UAVs), ranging from small drones to large person‐transport vehicles, continues to expand, detailed wind and turbulence observations near surface in urban areas are crucial for safe flight planning. In summer 2021, a field campaign was conducted in the suburbs of Seoul, South Korea, using a UAV equipped ...

Postfrontal Deep Convection Over the Southern Ocean and Orographic Precipitation Enhancement Over Tasmania

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The orographic precipitation enhancement (OPE) generated within wintertime post‐frontal air masses is a prominent climate feature of Tasmania. This study investigates a passage of a cold sector of a mid‐latitude cyclone over the Southern Ocean (SO) and Western Tasmania (WTAS) observed from 2100 UTC 11 July to 0300 UTC 13 July.

Influence of Emission Inventories and Secondary Organic Aerosol Chemistry on Simulated Fine Particulate Matter Over the U.S. in a Chemical Transport Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Accurately modeling ambient fine particulate matter (diameter <2.5 μm, PM2.5) is crucial to air quality management. We evaluate how uncertainties in biomass burning (BB) emissions, anthropogenic emissions, and secondary organic aerosol (SOA) production mechanisms impact simulated PM2.5 mass, composition, and statistical accuracy of modeled PM2.

Impacts of Maritime Continent Forest and Peat Fires on Regional Air Quality During 2019 CAMP2Ex Using MUSICAv0

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The NASA Cloud, Aerosol and Monsoon Processes Philippines Experiment (CAMP2Ex) field campaign from 24 August to 05 October 2019 observed a complex mixture of aerosols—biomass burning smoke transported from Maritime Continent (MC)/Indonesia fires to the Philippines and Metro Manila's urban pollution.
