An inversion represents a layer of the atmosphere in which the temperature gets warmer the higher you go. A variety of conditions can cause inversions, but most common in Arizona is the nighttime inversion. This is when a layer of cooler air is trapped near the ground by a layer of warm air above the surface. When the air cannot rise, pollution accumulates near the ground, leading to higher pollutant concentrations | Learn More about Inversions >
