Stratospheric Aerosol Particle Size Explains Divergent Limb and Solar Occultation Measurements After the Hunga Eruption

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The 2022 Hunga eruption significantly perturbed the stratosphere by injecting substantial water vapor and SO2 ${\text{SO}}_{2}$, drastically changing the Aerosol Optical Depth (AOD) and particle size. Post‐eruption, satellite limb‐scattering retrievals of aerosol extinction from Ozone Mapping and Profiler Suite Limb Profiler (OMPS‐LP) and ...

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 ...

Behavior of Nitrogen During AOD Process

ISIJ International, 2009
A computational model based on mass transfer and thermodynamic data as well as kinetic information from the industrial AOD process has been created in order to simulate the nitrogen content of the stainless steel melt as a function of blowing time. The model uses Butler's equation to calculate the reaction area available for nitrogen transfer between ...

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.

Quantifying Equilibrium Climate Sensitivity to Atmospheric Chemistry and Composition Representations in GFDL‐CM4.0 and GFDL‐ESM4.1

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Equilibrium climate sensitivity (ECS) quantifies surface warming in response to doubled pre‐industrial CO2 (2xCO2). Uncertainty in estimates arises from diverse model representations and climate‐chemistry feedbacks. We quantify ECS with five atmospheric chemistry‐composition model representations (sea salt, dust, organics, ozone, sea ice ...

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,

Hemispheric Synoptic Patterns Control Rainfall and Long‐Range Aerosol Transport in the Amazon

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The transatlantic transport of dust and smoke aerosols from Africa to South America is a large‐scale, year‐round process that affects atmospheric and nutrient cycling in the Amazon rainforest. We analyze daily variations in black carbon at the Amazon Tall Tower Observatory (ATTO) to investigate how Atlantic synoptic‐scale meteorology ...

Satellite Observations Show Negligible Impact of Mineral Dust on Cloud Droplet Number

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The susceptibility of cloud droplet number concentration Nd $\left({N}_{\mathrm{d}}\right)$ to aerosols (β) $(\beta )$ remains challenging to constrain in satellite observations. This difficulty arises from limitations in representing cloud condensation nuclei, which depend on aerosol size and composition.
