Marine Fog Observations in the Arctic.

Abstract

Shipboard measurements of meteorology, droplet physics, radiochemistry, and atmospheric electricity are described for three marine fog events which occurred in the Greenland Sea during August and September 1972. These measurements include air temperature, sky and sea surface temperatures, humidity, windspeed, atmospheric potential gradient, atmospheric radon concentrations, droplet concentrations, and droplet size spectrums. A variable-path-length Lyman-alpha absorption humidiometer is described which is used for fine structure analysis of water vapor in fogs. In all three events persistent fogs were observed to exist in a subsaturated atmosphere with a relative humidity of less than 95% during sizeable portions of the events. (Modified author abstract)
