Haze over the Mojave Desert from a brush fire in Santa Barbara, California, seen as the Sun descends on the 2016 June solstice, allows the Sun to be photographed without a filter. thumbnail|Bushfire haze in Sydney Australia. Haze as smoke pollution over the Mojave from fires in the Inland Empire, June, 2016, demonstrates the loss of contrast to the Sun, and the landscape in general. Haze causing red clouds, due to the scattering of  smoke particles, also known as Rayleigh scattering during Mexico's forest fire season. Haze  is traditionally an atmospheric phenomenon in which dust, smoke, and other dry particulates obscure the clarity of the sky. The World Meteorological Organization manual of codes includes a classification of horizontal obscuration into categories of fog, ice fog, steam fog, mist, haze, smoke, volcanic ash, dust, sand, and snow.WMO Manual on Codes Sources for haze particles include farming (ploughing in dry weather), traffic, industry, and wildfires . Haze in Monterrey, Mexico during grassland fires . Seen from afar (e.g. an approaching airplane) and depending on the direction of view with respect to the Sun, haze may appear brownish or bluish, while mist tends to be bluish grey. Whereas haze often is thought of as a phenomenon of dry air, mist formation is a phenomenon of humid air. However, haze particles may act as condensation nuclei for the subsequent formation of mist droplets; such forms of haze are known as "wet haze."
