Air mass is a relative measure of the optical length of the atmosphere. At sea level, when the sun is directly overhead (zenith angle = 0), the air mass is equal to 1. As the zenith angle becomes larger, the path of direct sunlight through the atmosphere grows longer and air mass increases. "Relative" air mass is only a []
