Aerosol dynamics and its implication for global aerosol climatology
This paper considers the effects of aerosol dynamics in the earth's atmosphere. In polluted regions, in-situ particle formation is expected to occur in combustion processes and in plumes, and coagulation is the major process by which particles grow large enough to be optically active or activated in clouds. Conversely, in unpolluted regions, new particle formation is less evident and cloud processing is the major mechanism by which active particles are formed. The paper further focuses on the remote marine aerosol produced from DMS, which highlights the multi-phase nature of aerosol dynamics and the fact that it is closely coupled to synoptic scale meteorological phenomena. An example is given of how aerosol dynamics have been introduced in a global transport model, and a first result shows that the upper free troposphere is an important area of new particle production.
