Measurements from three types of intertidal sites indicate that intertidal areas do not significantly contribute to the regional atmospheric sulfur budget. Dept., M. Planck Inst. An explicit microphysical model with size-resolved chemistry suggests that the presence of alkaline seasalt particles has a significant impact on the magnitude and properties of sulfate produced in clouds. N. Mihalopoulos et al., J. Atmos. 10Be was used as a spike of natural background atmospheric aerosol to calculate the global flux of sulfur into the free troposphere.
Results suggest that most of the sulfur emitted at ground level remains in the boundary layer.
The role of OCS in the upper tropospheric sulfur budget is reviewed, especially the significant impacts of volcanic eruptions. Cascade impactor samples are consistent with previous results suggesting that MSA produced from photochemical oxidation of DMS condenses preferentially on preexisting particles, implying that MSA may not contribute appreciably to enhancing CCN populations in the remote tropical marine atmosphere. Measurements of sulfur gases and fluxes during the past decade were combined to create a global emission inventory, which takes into account the seasonal behavior of biogenic sources.
