AB: We apply and extend recent results of Larsen et al. (2003), concerning spatial and temporal correlations among aerosol particles, to correlations among different size bins. The basic question addressed is: what should be a reasonable set of requirements on coherence vs. collection times, in order to define a physically meaningful notion of a size distribution and its time evolution? To that end, we present and examine new high temporal resolution aerosol data in the form of 5 contemporaneous time series, corresponding to five different aerosol size bins. We calculate cross-correlation functions among the different sizes and discuss the implications of variable coherence times on the notion of the aerosol size distribution. References: M.L. Larsen, W.
