, and H. Cheyney, 1968: Comments on the paper by D.G. Rea and B.T. O'Leary, "On the composition of the Venus clouds". J. Geophys. Res., 73, 6136-6137, doi:10.1029/JB073i018p06136.
In a recent paper Rea and O'Leary [1968] examined the cases for and against ice clouds on Venus and concluded that "there is no direct evidence for H2O ice crystals, and furthermore, if they do exist on Venus and dominate the near-infrared scattering process, they must be submicron in diameter." We believe that at least the latter of these two conclusions is not correct, because clouds composed of ice particles a few microns in diameter do not generally cause absorption features at 1.5 and 2.0 μ as strong as assumed by Rea and O'Leary. Their conclusion was based in part on laboratory reflectivity spectra obtained by Zander [1966], but we believe that Zander's reflectivity spectra are representative of particles larger by a factor of about 5 than suggested in Zander's publication.
