Airmass

/ˈɛərˌmæs/ noun

Definition

A measure of the amount of atmosphere through which light from a celestial object must pass to reach an observer, with airmass = 1 at the zenith and increasing toward the horizon. Used to calculate atmospheric extinction effects.

Etymology

Compound of 'air' from Old French 'air' and 'mass' from Latin 'massa', coined in the early 20th century as astronomers developed quantitative methods to account for atmospheric effects in photometry and spectroscopy.

Kelly Says

At the horizon, you're looking through about 40 times more atmosphere than straight up! This is why the Sun appears red at sunset and why stars seem much dimmer when they're low in the sky - you're seeing them through a much thicker blanket of air.
