Fig. 12

The probability distribution of a particle with the indicated settling velocity class included in the particles that arrived at each site in the first minute. For the case where the period is longer than 15 min when L_obs, L_cal1, and L_cal8 are also zero, the events are separated and those during which the particles in four or more settling velocity classes arrive are extracted. In each region (separated by dashed lines), the lower plots are the loads with lower settling velocities. The y-axis is the settling velocity of the particles (m s⁻¹)
