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.

Aerosol index is an ideal metric for tracking the evolution of episodic aerosol plumes from dust outbreaks, volcanic ash, significant fire events, and biomass burning. Those plumes can harm human and ecosystem health, disrupt the work of important industries, and pose significant hazards to transportation.
Aerosol particles are commonly assumed to be homogeneous spheres in the context of aerosol–radiation interactions. Under this approximation, Mie theory is used to describe mathematically the scattering and absorption of solar and terrestrial radiation. It finds that for a single particle the probability of scattering and absorption, their variations with wavelength, and the angular ...
Aerosol-cloud interactions (ACI) arise from aerosol perturbations that influence the number of cloud droplets and ice crystals, leading to corresponding microphysical and radiative effects (Gettelman, 2015). Clouds affect the energy balance in the atmosphere by regulating the flow of radiation at the top of the atmosphere.
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.
Stratospheric aerosol injection (SAI) is defined as a solar geoengineering technique that involves pumping sulfate aerosols into the stratosphere to decrease the amount of solar radiation reaching Earth's surface, thereby mimicking the natural cooling effects of volcanic eruptions.
