The 27-28 October 1986 FIRE IFO cirrus case study: Comparison of satellite and aircraft derived particle size [PDF]

Theoretical calculations predict that cloud reflectance in near infrared windows such as those at 1.6 and 2.2 microns should give lower reflectances than at visible wavelengths. The reason for this difference is that ice and liquid water show significant

Self‐Lofting Drives Tropospheric and Stratospheric Transport of Australian Wildfire Smoke to Antarctic Ice

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The 2019–2020 Australian New Year (ANY) wildfires injected vast amounts of aerosols and trace gases into the atmosphere. Previous studies focused on pyrocumulonimbus (pyroCb) activities that inject smoke directly into the upper troposphere. Our study shows that extensive aerosol plumes emitted into the lower troposphere during ANY wildfires ...

Global Diurnal Variation Characteristics of Aerosol Optical Depth From 32 Years of AERONET Observations

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Aerosols are ubiquitous microscopic particles in the atmosphere, and their diurnal variation characteristics reflect short‐term atmospheric changes that are crucial for climate monitoring and prediction. However, satellite, ground‐based, and reanalysis systems cannot simultaneously provide observational authenticity together with full temporal–

Anomalous Opaque Clouds Revealed by Collocated MODIS and CALIOP Retrievals

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract This paper examines discrepancies between cloud optical thickness (COT) retrievals from the Moderate Resolution Imaging Spectroradiometer (MODIS) cloud product, and cloud opacity measurements from the Cloud‐Aerosol Lidar with Orthogonal Polarization (CALIOP) lidar.

Effects of Volcanic Emissions on Clouds During Kilauea Degassing Events [PDF]

Aerosols influence Earths radiative balance directly by scattering and absorbing solar radiation, and indirectly by modifying cloud properties. Current scientific consensus indicates that these effects may offset as much as 50% of the warming due to ...

Air Quality Penalty in Southeast Asia Driven by AMOC Slowdown

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The Atlantic Meridional Overturning Circulation (AMOC) regulates Earth's climate by redistributing heat and freshwater across the Atlantic Ocean. While accelerating Arctic melt is expected to weaken the AMOC, its implications for atmospheric composition remain poorly understood.

Observing Systems Simulation Experiments of Hypothetical Hourly Global Coverage of Microwave Satellite Radiances: Imbalance and Adaptive Observation Error Inflation

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract This study investigates the potential impacts of frequent global coverage of satellite microwave radiances using a global atmospheric data assimilation (DA) system. Observing Systems Simulation Experiments (OSSEs) were performed using the Local Ensemble Transform Kalman Filter with the Nonhydrostatic Icosahedral Atmospheric Model (NICAM ...

Revisiting Intrinsic Predictability of Wave‐Convection Coupled Bands Over Southern China: Variable and Scale‐Dependent Error Growth Characteristics

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract This study investigates the variable‐ and scale‐dependent intrinsic predictability of wave‐convection coupled bands over southern China on 30 January 2018, using 1‐km simulations under varying initial moisture conditions. The predictability time is quantified via the Loss Predictability Index (LPI), defined as the ratio of the forecast error ...

Constraining the Aerosol Effects on Deep Convective Clouds by Considering the Coupling Between Clouds and the Planetary Boundary Layer

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Several mechanisms have been proposed for the aerosol invigoration effect. Although their principles are well established, their actual magnitudes and roles in cloud development remain uncertain and debatable. This uncertainty partly stems from observational‐based studies, in which it has been challenging to separate the co‐variability between

Contrail Formation Within Cirrus: Contrail Induced Perturbations and Cirrus Adjustments

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Contrail formation constitutes a large fraction of the aviation climate impact. But only part of the effect has been studied in detail, as research focused on contrail formation in cloud‐free air. Even though it is known that the impact of contrail formation within cirrus can be detected in space‐born remote sensing data, little research has ...
