A Decade of Airborne Electromagnetic Surveying Lake Menindee (Australia) Under Varying Water Levels

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT Time domain airborne electromagnetic (AEM) surveying is a mature geophysical tool for imaging the Earth's shallow subsurface. It produces images of the electromagnetic conductivity structure of the earth, down to depths of a few hundred metres.

Pedodiversity‐Based Covariates for Digital Soil Mapping Framework

European Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
ABSTRACT The integration of soil diversity as a covariate in digital soil mapping framework remains largely unexploited. However, we believe that it may carry important information that can be used to create more accurate digital maps of soil properties.

Turning Mediterranean Farmlands Into Priority Habitats: Natural Expansion of Juniper Woodlands After Agricultural Abandonment

Journal of Vegetation Science, Volume 37, Issue 3, May/June 2026.
Spanish juniper woodlands are expanding across central Spain as farmland is abandoned. By combining 34 years of land‐cover data with high‐resolution photogrammetry and field measurements, we show that juniper growth depends on topography, solar exposure and competition with shrubs. High irradiance increases biomass in older stands but limits young ones,

Airborne Photon‐Counting LiDAR for Shallow‐Water Bathymetry With Robust Noise Removal and Depth Retrieval

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Airborne photon‐counting LiDAR has emerged as a promising tool for shallow‐water bathymetry, offering high spatial resolution and penetration depth for coastal and nearshore applications. This study presents an integrated workflow for processing airborne photon‐counting LiDAR data to estimate shallow‐water bathymetry.

Observed and Modeled Changes in Boundary‐Layer and Surface‐Level Actinic Flux Due To Wildfire Smoke Plumes in the California Central Valley in Summer 2018

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Wildfire smoke is increasingly degrading U.S. air quality via the emission and transport of pollutants. Smoke's direct role as a pollutant is well‐documented; however, smoke also affects pollutant concentration indirectly by changing the shortwave actinic flux necessary for photochemical reactions.

Below‐Cloud CCN Concentrations Provide Better Constraints on the Twomey Effect Than Aerosol Optical Properties

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The primary uncertainty in anthropogenic climate forcing arises from a limited understanding of aerosol effects on cloud albedo, which in combination with other effects, is termed the radiative forcing from aerosol‐cloud interactions (RFaci).
