2000年8月23日 · The main aerosol property affecting the satellite signal is the aerosol optical depth (AOD, sometimes also called aerosol optical thickness—AOT). AOD is an optical measure of aerosol column amount, based on the light scattered and absorbed by airborne particles, and typically reported at a reference wavelength in the mid-visible part of the ...

2001年8月14日 · The term aerosol has been associated with F. G. Donnan in connection with his work on smokes during World War I. An aerosol is regarded as an analogy to a liquid colloidal suspension, sometimes called a hydrosol. These suspensions are relatively stable, with very low gravitational settling speeds and slow rates of coagulation.

The editors and editorial advisory board consider it the prime vehicle for the publication of original work as well as reviews related to fundamental and applied aerosol research, including aerosol instrumentation. Its content is directed at scientists working in engineering disciplines, as well as physics, chemistry, and environmental sciences.

2022年1月1日 · Aerosol precursor gases are gases that can partition into the particle phase (i.e., add to the existing particle mass) or participate in the formation of new particles by gas-to-particle conversion (nucleation, Section 5.2.2). Precursor gases are either emitted directly into the atmosphere, such as ammonia, or undergo gas-phase chemical ...

2024年1月1日 · Aerosols are important atmospheric constituents with significant impacts on both regional air quality and the global climate and environment. Aerosol effects on radiation, clouds and precipitation are strongly related to the optical properties of aerosols, which vary considerably in space and time.

2021年2月1日 · Aerosol climatic effects have also strong impacts on ET [5, 48, 56], though such impacts are dependent on location, vegetation, and aerosol loading. Observations showed that water-use efficiency, the ratio between photosynthesis and ET, is 5 and 3 times greater under thick cloud than under aerosol and thin cloud conditions at the forests in ...

2023年8月1日 · Aerosolization of immunotherapies poses incredible potential for manipulating the local mucosal-specific microenvironment, engaging specialized pulmon…

2024年8月16日 · NASA Worldview has expanded its suite of satellite-based remote sensing measurements of aerosol optical depth (AOD) and Angstrom parameter to include four new layers of ground-based measurements from the global Aerosol Robotic Network program. Users can now quickly and easily compare ground based measurements to satellite based …

2009年7月1日 · The quantitative measurement of aerosol light absorption is still a challenge. Simple, commonly used filter measurements are prone to measurement artifacts due to particle concentration and modification of particle and filter morphology upon particle deposition, optical interaction of deposited particles and filter medium, and poor angular integration of light …

1 Overview—The Need for Individual Particle Analysis. Atmospheric aerosol particles exist in a wide range of sizes, morphologies, and chemical compositions. 1–4 These primary particle properties determine their physical and chemical evolution as they are transported through the atmosphere and affect atmospheric chemistry, clouds, climate, human health, and ecosystems.
