Aerosols - NASA Earthdata Aerosols are tiny particles suspended in Earth's atmosphere There are two main types of aerosols: primary aerosols, such as sea spray, mineral dust, smoke, and ash, which become part of the atmosphere organically through natural processes Secondary aerosols, such as sulfate aerosols from volcanoes or industrial emissions, undergo chemical changes when introduced into the atmosphere that
Aerosol - an overview | ScienceDirect Topics Aerosol is defined as tiny solid or liquid particles suspended in a gas, often characterized by their size, such as those with a mean aerodynamic diameter that can affect deposition in various regions of the respiratory system AI generated definition based on: Fundamentals of Air Pollution (Fifth Edition), 2014
Journal of Aerosol Science | ScienceDirect. com by Elsevier An International Journal Founded in 1970, the Journal of Aerosol Science is the first journal specifically devoted to publishing research on the behavior of suspensions of particles and droplets in a gas, i e aerosols 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
Atmospheric aerosol spatial variability: Impacts on air quality and . . . Secondary aerosol formation depends on multiple factors, including the availability of precursors and atmospheric oxidants and meteorological conditions (solar radiation, relative humidity, cloud presence, and cloud liquid water content) The primary components of secondary inorganic aerosol are sulfates and nitrates
Aerosol optical and radiative properties and their environmental . . . Aerosol effects on radiation, clouds and precipitation are strongly related to the optical properties of aerosols, which vary considerably in space and time This study reviewed the current understanding of the optical and radiative properties of aerosols and aerosol effects in China, and presented future research prospects
Aerosol - an overview | ScienceDirect Topics 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
Study on global atmospheric aerosol type identification from combined . . . Accurate identification of aerosol types is essential for understanding the radiative properties of aerosols and further studying aerosol regional and global climate effects However, aerosol type identification studies combining satellite and ground observations are rare
Observational evidence and mechanisms of aerosol effects on . . . However, discrepancies exist among current studies due to aerosol properties, precipitation types, the vertical location of aerosols and meteorological conditions The development of technology has driven advances in current research, but understanding the aerosol effects on precipitation remain complex and challenging
Aerosol radiative and climatic effects on ecosystem productivity and . . . Aerosol-induced cooling has positive (negative) impacts on photosynthesis at low (high) latitudes The enhanced drought by aerosols may decrease both photosynthesis and evapotranspiration On the global scale, the net effects of aerosols on ecosystems are limited due to the offset of radiative and climatic effects
