Soluble species in the Arctic summer troposphere - Acidic gases, aerosols, and precipitation
The large-scale spatial distribution from 0.15-to 6 km altitude in the North American Arctic troposphere of several soluble acidic gases and major aerosol species during the summertime is reported. The distribution is found to be compositionally consistent on a large spatial scale. The summertime tr...
