Particle concentrations at the South Pole, on meteorological and climatological time scales; Is the difference important?

Abstract

Sulfur and dust layers in glacial ice cores have been associated with volcanic activity. Particles collected on the South Polar Plateau during January of 1983 show the maximum concentration of sulfur aerosol to arrive at the surface, from the lower troposphere at the beginning of a storm, and the maximum dust concentration to arrive from the upper troposphere as the storm weakens. The sulfur and dust particles did not arrive simultaneously on the meteorological time scale, posing a question to interpretation of the climatic aerosol record, and the glacio‐climatic record.
