An analysis of landslides in Great Britain using soil texture, rainfall and topography reveals contrasting failure conditions between organic and mineral soils

Earth Surface Processes and Landforms, Volume 51, Issue 4, April 2026.
Mineral and organic landslides from the BGS landslide database were each clustered into three distinct groups using landslide‐slope angle, rainfall on the day of the landslide, cumulative rainfall and soil texture. Differences between organic and mineral landslides as well as between landslide clusters were interpreted from a mechanistic viewpoint ...

Comparison of total ozone measurements in Melbourne, Australia, performed with a low-cost micro spectrometer and a Brewer MK-III [PDF]

Atmospheric Measurement Techniques
A new design for a simple and very low-cost instrument for measuring total column ozone is described and its performance evaluated by comparison to a co-located MK III Brewer spectrophotometer for approximately 6 months.

CNXT‐Ti‐LT–Based Multi‐Scale Feature–Aware Susceptibility Mapping of Rainfall‐Induced Clustered Landslides in Southeast China

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract This study focuses on the clustered landslide event triggered by intense rainfall on 16 June 2024 in the Fujian–Guangdong–Jiangxi border region, aiming to develop an efficient deep learning model for high‐accuracy landslide susceptibility mapping. Based on the mapped landslide distribution and insights from field investigations, we constructed

Improved hydrometeor detection near the Earth's surface by a conically scanning spaceborne W-band radar [PDF]

Atmospheric Measurement Techniques
The Earth's strong radar surface return limits the detection of clouds and precipitation in the lowest part of the atmosphere by nadir-pointing spaceborne radars such as CloudSat and EarthCARE.

A 30-month field evaluation of low-cost CO₂ sensors using a reference instrument [PDF]

Atmospheric Measurement Techniques
Low-cost, medium-precision sensor (LCS) networks have emerged as a promising approach for CO2 monitoring under complex urban emission conditions. However, the field performance of these LCSs faces significant challenges from environmental factors (e.g ...

Assimilation of global navigation satellite system (GNSS) zenith delays and tropospheric gradients: a sensitivity study utilizing sparse and dense station networks [PDF]

Atmospheric Measurement Techniques
The assimilation of global navigation satellite system (GNSS) zenith total delays (ZTDs) into numerical weather models improves weather forecasts. In addition, the GNSS tropospheric gradient (TG) estimates provide valuable insight into the moisture ...

Turbulent enhancement ratios used for characterizing local emission sources in a complex urban environment [PDF]

Atmospheric Measurement Techniques
In this study, we introduce the turbulent enhancement ratio (TER) as an experimental approach for characterizing local emission sources in complex urban environments, with a focus on the city of Innsbruck, Austria. The idea behind the approach is to take

Lagrangian aerosol particle trajectories in a cloud-free marine atmospheric boundary layer: implications for sampling [PDF]

Atmospheric Measurement Techniques
Meteorological processes such as gust fronts, roll structures, internal boundary-layer development and smaller-scale turbulence complicate the physical interpretation of measured aerosol particle properties, fluxes, and transport in the marine ...

Comparison of the performance between three Doppler wind lidars and a novel wind speed correction algorithm [PDF]

Atmospheric Measurement Techniques
Doppler wind Lidars (DWLs) have been widely used to detect wind vector variations, based on ground monitoring of atmospheric boundary layer and wind shear. This study evaluates the performance between three DWLs and in situ balloon radiosonde.
