MODELING A CASE OF PARTICLE NUCLEATION IN THE MARINE BOUNDARY-LAYER

A diagnostic modeling study is performed on a hypothesized case of particle nucleation in the marine boundary layer. A three-mode integral nucleation model is used and predicts particle concentrations in accord with observations when initialized with the appropriate field measurements. Further analysis of the data suggests the conditions favorable for nucleation at the surface were due to mixing of air at the top of the boundary layer down to the surface.
