Number size and surface area distributions for the Ann Arbor rain samples from a) June and b) July collected using the NTA. The dashed (red) lines are log-normal fits for the number size and surface area distributions and the (grey) shaded regions indicate the ± 1 standard error of the mean. c) The total number concentration and surface area of particles from all 4 precipitation samples is given with standard error and includes the fractional break down of large (>300 nm) and small (<300 nm) particles.
