Interstellar Dust Close to the Sun [PDF]

open access: yes, 2012
The low density interstellar medium (ISM) close to the Sun and inside of the heliosphere provides a unique laboratory for studying interstellar dust grains.

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

open access: yesGeophysical 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

open access: yesGeophysical 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–

X-Ray Absorption and Scattering by Interstellar Grains

open access: yes, 2016
Interstellar abundance determinations from fits to X-ray absorption edges often rely on the incorrect assumption that scattering is insignificant and can be ignored.

The Physical Structure of Protoplanetary Disks: the Serpens Cluster Compared with Other Regions [PDF]

open access: yes, 2012

Anomalous Opaque Clouds Revealed by Collocated MODIS and CALIOP Retrievals

open access: yesGeophysical 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.

Air Quality Penalty in Southeast Asia Driven by AMOC Slowdown

open access: yesGeophysical 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.

Compositional characterisation of the Themis family

open access: yes, 2015
Context. It has recently been proposed that the surface composition of icy main-belt asteroids (B-,C-,Cb-,Cg-,P-,and D-types) may be consistent with that of chondritic porous interplanetary dust particles (CPIDPs). Aims.

Observational Evidence for Relative Humidity Driving Black Carbon Mixing State and Absorption Enhancement in Urban Outflows

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Black carbon (BC)‐containing particles are the most strongly absorbing component of atmospheric aerosol, contributing to global warming. Quantifying their radiative effects remains challenging because BC absorption depends on their mixing state which can evolve through atmospheric aging.

Crystalline Silicate Emission in the Protostellar Binary Serpens--SVS20

open access: yes, 2005
We present spatially resolved mid-infrared spectroscopy of the class I/flat-spectrum protostellar binary system SVS20 in the Serpens cloud core. The spectra were obtained with the mid-infrared instrument T-ReCS on Gemini-South.
