| Abstract: | Relationships among atmospheric CO2 concentration, excess sulfate and vanadium, and meteorological analyses for one winter at Barrow, Alaska were investigated. The results provided a basis for understanding the causes of short term CO2 variability. The study indicated that peaks in CO2 concentration were related to direct atmospheric transport of industrial pollutants from Eurasia. Evidence that background Arctic concentrations contained a pollution component was also found. Lowest CO2 concentrations occurred with intrusions of Pacific air above the surface-based polluted Arctic air mass. |
