Atmospheric condition is a term used to describe the physical characteristics of the air around us. Two common atmospheric conditions are HAZE and SMOG. HAZE is a type of air pollution that is caused by tiny particles suspended in the air, which can reduce visibility and cause irritation to the eyes and throat. SMOG is a type of air pollution that is caused by a combination of smoke and fog, and is often seen in large cities due to the high levels of emissions from vehicles and factories.
