Abstract [en]

Abstract Simultaneous measurements of elemental carbon (EC) concentrations in air and in fresh snowfall were made for six storms during the spring of 1984 in the Swedish Arctic. Air concentrations ranged from 0.8-0.05 um^-3, while concentrations in the fresh snowfall ranged from 60-4 ul^-1 meltwater with a marked decrease in both the air and snow concentrations over the sampling period. The EC scavenging ratio in the snowfall remained roughly constant at ca 100 and appeared to be independent of these concentration changes. In addition to the EC measurements pH, conductivity, and some major ions were measured in the fresh snowfall. Excess sulfate varied from 0-12 uM with the lowest value at the end of the sampling period, while pH ranged from 4.6-5.2, with the highest values at the end of the sampling period.
