The purpose of the report is to point out one consequence of the discovery of HCl and HF in the Venus atmosphere, namely, that on account of the presence of HCl there cannot be much liquid water in the atmosphere. HCl is highly soluble in water, and the resulting acid has a high DC conductivity. If there were much of this acid in the Venus atmosphere, the long wavelength radar signals would be strongly attenuated, whereas the radar signals appear to reach the planets surface with little attenuation.
