One major characteristic of aerosols in the atmosphere is their ability to influence temperature conditions. Aerosols are tiny particles or droplets suspended in the air, which can either cool or warm the Earth's surface depending on their properties and interaction with sunlight. For example, certain aerosols can reflect sunlight back into space, leading to a cooling effect, while others can absorb heat, contributing to warming. This ability to modify both incoming solar radiation and outgoing infrared radiation plays a significant role in climate and weather patterns.

In contrast, the other options do not accurately describe the nature of aerosols. It is incorrect to say they only absorb heat, as their effects can range widely in terms of radiative forcing. Also, aerosols are not limited to liquid particles; they can be solid or liquid, and can consist of a variety of chemical compositions. Lastly, saying they never affect solar radiation overlooks their crucial role in scattering and absorbing sunlight. Thus, the characteristic of influencing temperature conditions encapsulates the dynamic and multifaceted roles aerosols play in atmospheric phenomena.
