Modeling Large Dust Aerosols in the Community Earth System Model Version 2 (CESM2)

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract Dust aerosols have a wide size distribution from less than 0.1 to over 100 μm and dominate Earth's atmospheric aerosol mass. However, most Earth system models (ESMs) inadequately represent dust aerosols larger than 10 μm in diameter, limiting the accuracy of the simulated dust cycle and climate impacts.

Deriving All‐Hour Aerosol Optical Depth Over China From Automated Visibility Observations

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract All‐hour aerosol monitoring remains challenging due to limited spatiotemporal coverage of current observational systems. Here we developed a machine‐learning based framework that derives 24‐hr aerosol optical depth (AOD) from automated visibility measurements.

Improving Aerosol Absorption Estimates Via Size‐Resolved Constraints Based on AERONET and In Situ Measurements

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Accurate aerosol particle size distribution is essential for estimating radiative forcing but is often hindered by assumptions that oversimplify more physical approximations of aerosol mixing state and size. This work performs a single‐site observational‐closure study that combines AERONET multi‐wavelength extinction and absorption retrievals,

Trend of North African Dust Storms and Potential Link to Climate Change

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract Over recent decades, North African dust storms have undergone marked variability, reflecting complex interactions between regional climate processes and environmental change. Using four decades (1984–2023) of visibility‐based observational records, we examine regional and seasonal trends in dust storm frequency across the Sahel and the Sahara,

The Reflectance Distribution of Shallow Cumulus and Its Environs From High Spatial Resolution ASTER Images

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract We investigate the 1D reflectance distribution of shallow cumulus as a function of cloud size, using high‐spatial‐resolution observations from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). Reflectance transects through clouds are compared between Inner Mongolia and Tropical Ocean.

A Short Note on the Potential of Utilization of Spectral AERONET-Derived Depolarization Ratios for Aerosol Classification

Atmosphere, 2019
We herein present the spectral linear particle depolarization ratios (δp) from an Aerosol Robotics NETwork (AERONET) sun/sky radiometer with respect to the aerosol type. AERONET observation sites, which are representative of each aerosol type, were

Using MODIS and AERONET to Determine GCM Aerosol Size

Journal of the Atmospheric Sciences, 2006
Abstract Aerosol size is still a poorly constrained quantity in general circulation models (GCMs). By using the modal radii of the coarse and fine mode retrieved from 103 stations in the Aerosol Robotic Network (AERONET) and the fine mode aerosol optical depth fraction derived from both the Moderate Resolute Imaging Spectroradiometer ...

Consistency of Aerosol Optical Properties between MODIS Satellite Retrievals and AERONET over a 14-Year Period in Central–East Europe

Remote Sensing
Aerosols influence Earth’s climate by interacting with radiation and clouds. Remote sensing techniques aim to enhance our understanding of aerosol forcing using ground-based and satellite retrievals. Despite technological advancements, challenges persist

Comparison of Columnar, Surface, and UAS Profiles of Absorbing Aerosol Optical Depth and Single-Scattering Albedo in South-East Poland

Atmosphere, 2019
The impact of absorbing aerosols on climate is complex, with their potential positive or negative forcing, depending on many factors, including their height distribution and reflective properties of the underlying background.
