Abstract: Spectral reflectances have been calculated by accepted methods for water cloud layers having various microphysical properties. We show that spectral reflectance measurements carried out with realistic accuracy at wavelengths ...

Abstract: Cloud nucleus concentration measurements made at hourly intervals between 1968 and 1973 at Robertson, N. S. W., show a very clear diurnal pattern with a maximum at approximately 1800 local time and a minimum at 0600 local ...
