The examination of the air or atmosphere, especially to study its properties or detect substances in it.
From Greek 'aero-' (air) combined with '-scopy' (examination or observation). The word emerged in the 19th century as scientists developed methods to study atmospheric composition and properties.
Aeroscopy is like using a microscope for the sky—instead of looking at tiny things, scientists examine invisible air currents, pollution particles, and gases floating above us. This became crucial during the industrial revolution when cities needed to understand what their factories were pumping into the atmosphere.
