Histograms and fitted curves give frequency of occurrence of aerosol single scattering albedo values
derived from nephelometer and absorption photometer measurements on RV Vodyanitskiy in ACE-2
(June-July 1997, z=10 m asl, RH=55%, lambda=550 nm) by Quinn et al. (2000). Data points labeled
O&N00 are from nephelometer and absorption photometer measurements on Pelican A/C by Ostrom
& Noone (2000).
