Haze causes issues in the area of terrestrial photography and imaging, where the penetration of large amounts of dense atmosphere may be necessary to image distant subjects. This results in the visual effect of a loss of contrast in the subject, due to the effect of light scattering and reflection through the haze particles .
Transboundary haze in Southeast Asia has been recorded since 1972 [6] with the 1997 and 2015 events being particularly severe. [7] Industrial-scale slash-and-burn practices to clear land for agricultural purposes are a major cause of the haze, particularly for palm oil and pulpwood production in the region.
Arctic haze is the phenomenon of a visible reddish-brown springtime haze in the atmosphere at high latitudes in the Arctic due to anthropogenic [1] air pollution.A major distinguishing factor of Arctic haze is the ability of its chemical ingredients to persist in the atmosphere for significantly longer than other pollutants.
The 2015 Southeast Asian haze was an air pollution crisis affecting several countries in Southeast Asia, including Brunei, Indonesia (especially its islands of Sumatra and Borneo), Malaysia, Singapore, southern Thailand, Vietnam, Cambodia and the Philippines.
A NASA satellite image of the haze on 19 June 2013. The extent of the haze as of 19 June 2013. [1] The extent of the haze as of 23 June 2013. [1]The 2013 Southeast Asian haze was a haze crisis that affected several countries in Southeast Asia, including Brunei, Indonesia, Malaysia, Singapore [2] and Southern Thailand, mainly during June and July 2013.
Forest fires in Indonesia cause the trans-boundary haze in Indonesia, Malaysia, and Singapore almost every year. These fires clear land for palm oil plantations , and are known to be started by smallholding subcontractors who supply large companies that claim to discourage the practice but admit the chain of custody is a "complicated web."
This effect is known as the Harmattan haze. It costs airlines millions of dollars in cancelled and diverted flights each year. [9] [10] When the haze is weak, the skies are clear. [11] The extreme dryness of the air may cause branches of trees to die. [12]
These small solid particles cause the liquid to appear turbid. Turbidity (or haze) is also applied to transparent solids such as glass or plastic. In plastic production, haze is defined as the percentage of light that is deflected more than 2.5° from the incoming light direction. [1]
