The Life Cycle of a Stratospheric Smoke Plume as Seen From EarthCARE—Tracking a Plume From Canada to Europe

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract At the end of May 2025, extremely strong wildfires in Canada produced several pyrocumulonimbus clouds lifting the smoke particles up to the lower stratosphere. Stratospheric aerosol optical depths of more than 2.5 were observed by the ATmospheric LiDAR (ATLID) onboard of the Earth Cloud, Aerosol and Radiation Explorer (EarthCARE) satellite ...

Strong Ventilation Drives the Aerosol Pollution Receptor Center and Its Interannual Variability in Central China's Twain‐Hu Basin

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract This study investigates the unique winter phenomenon in central China's Twain‐Hu Basin where high aerosol optical depth (AOD) centers coincide with a regional near‐surface wind speed maximum. Based on multi‐decadal reanalysis data sets, satellite retrievals, ground observations, and FLEXPART‐WRF simulations, we demonstrate that strong ...

A Novel Methodology for Probing the Observed Influence of the QBO on Tropical Tropospheric Climate

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract The stratospheric Quasi‐Biennial Oscillation (QBO) is characterized by descending bands of wind and temperature anomalies in the tropical stratosphere with a mean period of ∼28 months. Numerous studies have argued that the QBO has a significant impact on tropical tropospheric climate.

Height‐Dependent Sensitivity of Cloud Scales to Surface Temperature Anomaly Observed by Active Satellites

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract As a key macrophysical property, cloud horizontal scale plays a critical role in cloud radiative effect (CRE), precipitation and convective structures. Until now, however, how cloud scales vary with surface temperature anomaly and their subsequent impacts on CRE and precipitation remains unclear.

Model simulations of complex dust emissions over the Sahara during the West African monsoon onset [PDF]

, 2012
The existing limitations in ground-based observations in remote areas in West Africa determine the dependence on numerical models to represent the atmospheric mechanisms that contribute to dust outbreaks at different space-time scales.

Efficient Retrieval of Subpixel Cloud Fraction From Coarse Cloud Masks Using Dual‐Branch Deep Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Cloud detection is a critical procedure in satellite remote sensing. Most meteorological satellite products provide binary cloud masks, which identify whether a pixel in the satellite image is entirely cloudy or clear‐sky, and the subpixel cloud fraction (CF) of partly cloudy pixels is usually unavailable.

How do CMIP6 Models Represent the Vertical Structure and Chemical Properties of Biomass‐Burning Aerosols Emitted in Central Africa?

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract CMIP6 climate models have difficulties representing the strong absorption properties of biomass‐burning aerosols (BBA) over the Southeast Atlantic and the associated direct forcing. This study takes advantage of unique in situ and remote sensing observations to evaluate the vertical profile and chemical composition of BBA, which are key ...
