Description
Summary:Through use of a documented interpolation scheme air parcel trajectories reaching the University of Minnesota Particle Technology Laboratory's mobile van on 20 September 1972 have been estimated. The close similarity of all trajectories during the early morning confirms the hypothesis of Whitby et al. (1975), that observed aerosol changes during early morning were not due to changes in the general source region of the sampled air parcels. Trajectory analyses for late morning and afternoon indicate the urban aerosol cloud boundary passed the laboratory shortly after 13:00h PST, not with the sea-breeze at 11:00h PST. Thus, 1300 marks the initial influx of air which had been over the open sea for a relatively long period. Examination of the aerosol measurements shows that some of their variability can be ascribed to the later air mass change.
