Polarized light scattering by aerosols in the marine atmospheric boundary layer [PDF]

open access: yes, 1997
The intensity and polarization of light scattered from marine aerosols affect visibility and contrast in the marine atmospheric boundary layer (MABL).

Chemical ageing and transformation of diffusivity in semi-solid multi-component organic aerosol particles [PDF]

open access: yes, 2011
Recent experimental evidence underlines the importance of reduced diffusivity in amorphous semi-solid or glassy atmospheric aerosols. This paper investigates the impact of diffusivity on the ageing of multi-component reactive organic particles ...

Characterization of Aerosol Hygroscopicity Over the Northeast Pacific Ocean: Impacts on Prediction of CCN and Stratocumulus Cloud Droplet Number Concentrations

open access: yesEarth and Space Science, 2020
During the Marine Aerosol Cloud and Wildfire Study (MACAWS) in June and July of 2018, aerosol composition and cloud condensation nuclei (CCN) properties were measured over the N.E.

Development of an In Vitro System to Study the Interactions of Aerosolized Drugs with Pulmonary Mucus

open access: yesPharmaceutics, 2020
Mucus is the first biological component inhaled drugs encounter on their journey towards their pharmacological target in the upper airways. Yet, how mucus may influence drug disposition and efficacy in the lungs has been essentially overlooked.

Constraints on climate forcing by sulphate aerosols from seasonal changes in Earth's spin [PDF]

open access: yes, 2014
Angular momentum exchanges between atmosphere and solid Earth are strongly modulated by variations in global atmospheric circulation. Geodetically determined length-of-day (LOD) fluctuations provide an independent resource to investigate climate ...

Airborne environmental DNA metabarcoding for the monitoring of terrestrial insects—A proof of concept from the field

open access: yesEnvironmental DNA, 2022
Biodiversity is in decline due to human‐induced pressures on ecosystems around the world. To be able to counteract this alarming trend, it is paramount to closely monitor biodiversity at global scales.

Nitric acid scavenging by mineral and biomass burning aerosols [PDF]

open access: yes, 1998
The abundance of gas phase nitric acid in the upper troposphere is overestimated by global chemistry-transport models, especially during the spring and summer seasons.

Observed and CMIP5‐Simulated Radiative Flux Variability Over West Africa

open access: yesEarth and Space Science, 2020
We explore the ability of general circulation models in the Coupled Model Intercomparison Project (CMIP5) to recreate observed seasonal variability in top‐of‐the‐atmosphere and surface radiation fluxes over West Africa.

Wavelength dependence of the optical depth of biomass burning, urban, and desert dust aerosols

open access: yes, 1999
The Angstrom wavelength exponent α, which is the slope of the logarithm of aerosol optical depth (τ a ) versus the logarithm of wavelength (λ), is commonly used to characterize the wavelength dependence of τ a and to provide some basic information on the

Geoengineering: Whiter skies? [PDF]

open access: yes, 2012
One proposed side effect of geoengineering with stratospheric sulfate aerosols is sky whitening during the day and afterglows near sunset, as is seen after large volcanic eruptions.
