SAM computes and displays Optical
Depth, Angle Forward scattering, and Partial Size
Distribution approximately every 10 sec
figure the first and the last observations from
the above plots was used to fit a power-law curve
to derive particle effective radius:
slope of the particle size distribution is an indication of the relative
prevalence of large particles, with shallower slopes
indicating increased abundances of large particles.
