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 attenuation of light transmitted through a deposit of these particles increases linearly with the frequency of the electromagnetic radiation, i.e. inversely with respect to wavelength. Aethalometer measurements of optical attenuation on a filter deposit will increase at shorter wavelengths as λ (-α) where the parameter α (the Angstrom ...
Glenn Edmond Shaw is an American scientist specializing in atmospheric physics, especially relating to global climate change and long-range transport of aerosol material. He is Emeritus Professor of Physics and Atmospheric Science at the University of Alaska Fairbanks and a member of the scientific staff of the Geophysical Institute.
Mitchell's investigation of Arctic haze in the 1950s found aerosol particles which apparently originated from industrial areas of Europe and China. [1] Using studies of nuclear fallout from bomb tests which showed how aerosols moved in the upper atmosphere, he compared global temperature statistics with the record of volcanic eruptions in a 1961 paper which put forward his view that large ...
Arctic haze contributes to global warming, raising temperatures by up to 5.4°F (3°C) during the arctic winter? A major distinguishing factor of Arctic haze is the ability of its chemical ingredients to persist in the atmosphere for an extended period of time compared to other pollutants.
These easy New Year's appetizer recipes, like fondue bites and shrimp cocktail, will keep the party going all night as you ring in New Year 2025.
Black carbon was identified in the Arctic haze aerosols [21] and in the Arctic snow. [ 22 ] In general, aerosol particles can affect the radiation balance leading to a cooling or heating effect with the magnitude and sign of the temperature change largely dependent on aerosol optical properties, aerosol concentrations, and the albedo of the ...
Reflection Haze is an optical phenomenon usually associated with high gloss surfaces, it is a common surface problem that can affect appearance quality. The reflection from an ideal high gloss surface should be clear and radiant, however, due to scattering at imperfections in the surface caused by microscopic structures or textures (≈ 0.01 mm wavelength) the reflection can appear milky or ...
