Arctic Haze: A Chemical, Physical, Optical and Meteorological Study

During April and May 1976, bands of Arctic haze over Barrow, Alaska were studied by means of a light aircraft. The program included condensation- nucleus counts, radiation measurements, and filter samples for elemental analysis. Layers of Arctic haze were definitely present during the five-seek peri...

Description
Summary:During April and May 1976, bands of Arctic haze over Barrow, Alaska were studied by means of a light aircraft. The program included condensation- nucleus counts, radiation measurements, and filter samples for elemental analysis. Layers of Arctic haze were definitely present during the five-seek period, and were equally detectable by eye or with nucleus counts. A single major episode of haze bands occurred, associated with winds from the south. Analysis of these particles by neutron activation showed them to be mainly soil dust during the episode and pollution aerosol before and after. The origin of the dust was proposed as deserts in eastern Asia. (Author) A progress report and research proposal to the Office of Naval Research, Arctic Program.
