Atmospheric dust aerosol over the Tibetan Plateau

Journal of Geophysical Research: Atmospheres, 2001
Cascade impactor and bulk samples of atmospheric aerosol particles were collected at three sites on the Tibetan Plateau: Udaoliang (September 1993 to May 1994) and Lhasa and Gongga (May 1998). The average dust concentration at these groundbased sites was 82 μg m−3; this is lower than the lowest average concentration observed over the nine major Chinese

Lipidome of Saharan dust aerosols

Lipidomics, a subfield of metabolomics, is an emerging field where hundreds to thousands of lipid species are simultaneously identified. Given the ubiquity and diverse biological roles of lipids, lipidomics offers valuable insights into mechanisms and the discovery of biomarkers related to environmental stressors that affect the cellular physiology and

Dust Aerosol Important for Snowball Earth Deglaciation

Journal of Climate, 2010
Abstract Most previous global climate model simulations could only produce the termination of Snowball Earth episodes at CO2 partial pressures of several tenths of a bar, which is roughly an order of magnitude higher than recent estimates of CO2 levels during and shortly after Snowball events.

[Particles. Aerosols. Dust (author's transl)].

Le Poumon et le coeur, 1981
After a few definitions and generalities about aerosols, the main physical properties of aerosols are reviewed: sedimentation, diffusion, coagulation, optical and electrical properties. The properties of atmospheric aerosol are also summarized.

Planetary aerosol monitor/interplanetary dust analyzer

2002
The Laboratory for Astrophysics at the University of Florida has developed a dust analyzer capable of measuring key particle physical parameters without destruction or alteration of the dust grains. A laser illuminates dust grains passing through the device and a set of detectors obtains intensity and polarization of the scattered light at specific ...

Models of Stratospheric Aerosols and Dust

1982
This chapter deals with the structure and practical use of stratospheric aerosol models. The general mathematical framework of such models is developed, and several published models are reviewed. Applications and results of previous theoretical aerosol studies are discussed. Model predictions of aerosol physical properties, and of aerosol precursor gas

Natural Aerosolic Mineral Dusts and Human Health

2012
Fine atmospheric dust (including fine mineral aggregates, fibrous minerals, and fibrous organic materials) reaches concentrations in many parts of the world sufficient to constitute a major influence upon both human and animal health.
