Strong Diurnal‐Dependent Meteorological Control on Long‐Term Variations of Cloud Droplet Number Concentration

open access: yesGeophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract While long‐term cloud droplet number concentration (CDNC) changes are commonly attributed to aerosols, the role of meteorological factors remains poorly explored. Here, we perform a time‐resolved contribution analysis of long‐term CDNC variations using nearly two decades of geostationary observations over four Atlantic subtropical regions. The

Dust Layer Height Leads Atmospheric Boundary Layer Height by 3 hr Over the Taklimakan Desert

open access: yesGeophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The vertical distribution of dust modulates its radiative forcing and long‐range transport, yet the diurnal relationship between dust layer height (DLH) and atmospheric boundary layer height (ABLH) remains poorly constrained by observations.

Black Carbon Absorption Enhancement During Particle Aging Is Constrained by Size‐Dependent Morphological Transition Thresholds

open access: yesGeophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Quantifying the climate effects of black carbon (BC) requires resolving how atmospheric aging modifies the mixing state and light absorption of BC‐containing particles. Here, we optimize a tandem DMA‐SP2 system to obtain size‐resolved coating amount (MR) and morphology of BC‐containing particles.

Temperature Dependent Complex Refractive Index (CRI) of Hexagonal Ice in the Range 150–270 K: Infrared and Far‐Infrared Transmission Measurements at the AILES Beamline

open access: yesGeophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The complex refractive index (CRI) of ice is one of the main parameters driving the optical properties of ice clouds and frozen surfaces, hence their climate impact. While already characterized at short wavelengths, ice CRI has never been measured across the infrared range at temperatures relevant to Earth.

Methane Emissions From Wildfires: Trends and Anomalies

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Wildfires emit smoke particles and trace gases including greenhouse gases into the atmosphere, impacting the environment and leading to detrimental impacts on human health and economy. The estimation of spatially and temporally resolved methane emissions from biomass burning (BB) provides critical information in developing measurement‐informed
