Atmospheric Dynamics of IR‐Active Particles Released From Mars' Surface

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Surface release of radiatively active particles, with high infrared‐ (IR‐)to‐visible extinction ratios, has been proposed as a method of warming Mars. However, to warm Mars using aerosols, particles released locally must disperse globally. Here we provide an initial reference study in a plume tracking, dry Martian atmospheric model to address ...

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.

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 ...

Monte Carlo Simulation of 3D Cloud Radiance Distributions Affected by Ground‐Based Lighting

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Satellite observations of artificial light sources at night are increasing. Clouds, as the most important radiative modulators in the Earth‐atmosphere system, significantly influence the observed values and spatial distribution of the artificial light coming from the ground.

Distinguishing Between the Short‐Term Climate Responses to Different Stratospheric Aerosol Injection Latitudes With Explainable Artificial Intelligence

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Stratospheric aerosol injection (SAI), whereby reflective particles are released into the stratosphere to induce cooling, is one possible tool to counteract global warming and its associated risks. However, there is much uncertainty surrounding how SAI would be deployed, as well as the potential of novel and unknown risks and impacts.

Development of Broadband Aerosol Optical Depth Models

, 2016
In meteorological practice the Sun is considered as a stable source of light. The amount of broadband solar energy encompassing all wavelengths, incident on a unit area at the top of the atmosphere (TOA) may be calculated with a high precision. The ratio between the solar intensity at the Earth’s surface after attenuation in the air, and this at the ...

Large Eddy Simulation of Mixed‐Phase Clouds With Aerosol Perturbation: Importance of Effective Radius

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Aerosol‐cloud interactions are a major source of uncertainty in estimating anthropogenic effective radiative forcing. Although warm polluted clouds have been studied to investigate the influence of aerosols on clouds, studies on mixed‐phase polluted clouds are limited. Here we performed Large Eddy Simulations of mixed‐phase clouds with various

Coral δ13C Reveals Little Ice Age Dimming of Tropical Surface Shortwave Radiation Not Captured by Climate Models

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Tropical low‐cloud feedback is the largest source of uncertainty in climate sensitivity, yet multi‐century records of surface shortwave radiation are scarce. We calibrate Porites coral δ13C against satellite photosynthetically available radiation (PAR) and reconstruct monthly PAR for the northern South China Sea during the Medieval Climate ...
