Figures & data

FIG. 1 Aerosol number distribution functions measured with three instruments during nucleation events in Atlanta, GA on August 7 and 23, 2009. On August 7, the Cluster CIMS carried out sequential scans of all masses from 200 to 500 followed by selected ion measurements at 160, 293, and 391. On August 23, only selected ion measurements were done. The estimated uncertainties shown for 9:35 on August 23 apply to all data. Times shown are local standard time.
