PASE

The Pacific Atmospheric Sulfur Experiment (PASE) was a comprehensive study of the chemistry of sulfur in the remote marine troposphere. A major part of PASE was devoted to the chemistry and physics (primarily of sulfur) in a cloud free convective boundary layer (CBL). During the first phase, PASE investigators studied the chemistry and physics of gases and aerosols in a cloud free environment. During Phase II, the PIs focused on developing a better understanding of the formation of new particles in the cloud outflow of marine cumulus.
