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.
Shaw, working with Kenneth Rahn and using neutron activation technique as a chemical fingerprint identified the source regions of haze that builds up in the Arctic. They found the haze was confined within the boundaries of the Arctic Front, which expands in area to a maximum in spring months. [16]
Increasing interest in studies of phenomena such as Arctic haze led to a conference in 1977 in Lillestrøm, Norway with participation from scientists of seven different countries. Following this conference, the Arctic Air-Sampling Network (AASN) was created to share data between scientific organizations in each member nation. [6]
March is often a month of wild temperature swings, and this year has been no different. AccuWeather forecasters say that harsh cold will send temperatures trending downward through the remainder ...
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 ...
In parts of South and Middle Georgia, residents woke up this morning to hazy skies — a result of a renewed blanketing of the Southeast by Canadian wildfire smoke.
Cover outside water spigots. Before the temperature drops below 32 degrees, outdoor water spigots attached to homes should be opened to allow to drain water out, closed and then covered.
This 7 by 3 mile kidney-shaped iceberg was discovered near the North Pole by researchers studying the Arctic haze during the spring and summer. Although the thickness of the iceberg was 125 feet and it weighed over seven billion tons, it rose only ten feet above the surrounding ice packs and was virtually indistinguishable from the pack ice at ...
