Scatterplots between the absolute scavenged number fraction (Absolute SNF) and the SSlsd value estimated for a all rainfall events (N = 37) and b rainfall events with CPI > 0.5 (N = 23). Each open circle (triangle) indicates the results for a single rainfall event in Tokyo (Okinawa). The same analysis was performed using each of the four indicated distinct small-tracer Dtr values. The filled circles and error bars represent the median values and the 25th–75th percentile range
